Introduction

INTRODUCTION Solar control unit is intended for heating the DHW tank, accumulation tank (with or without built-in DHW tank) or swimming pool through solar collectors and / or boilers and / or el. heaters. The control unit can control heating up to 4 different tanks / swimming pool that can be heated up to 2 separate hot water solar collector fields and up to 2 types of conventional source (boilers) or el. heater. Pumps to collector can be operated with PWM or analog signal. In addition to the temperature sensors, also on the control unit it is possible to connect the flow meter and the pressure switch in the solar system. With standard tank heating control over temperature difference, control unit has protective functions such as collector cooling (over tank), collector freezing options, tank cooling (over collector or recirculation), legionella protection (disinfection function) and protection of outlets (pumps and valves ) of blocking due to long-term non using time. Also, it is possible to include the functions of examination of the priority tank filling, pumps pulse start, as well as annual holiday option (all protective functions are switched on at once), one-time heating of the tank, one-time extension of tank heating or tank disinfection ( legionella protection ). For the functions like heating of the tank with conventional source ( boiler ) or el. heater, recirculation, impulse start of the solar collector and disinfection of the tank it is possible to set schedual (timers) (two tables, for each day of the week, up to 3 times). All functions are controlled through a touch screen color screen that simplifies the use of control. As an additional equipment, a Cm WiFi-box can be connected via which it is possible to connect control unit to the local WiFi network for remote control and monitoring of the system.

Control unit description

CONTROL UNIT DESCRIPTION CmSOL control unit can control solar heating up to 4 separate tanks with 1 or 2 solar collector fields and heating the first tank using conventional sources - an el. heater and up to two boilers. Control unit has 10 inputs and 8 outputs. Types of solar collectors can be chosen between flat plate and vaccum tube solar collectors. Types of tanks can be selected between DHW tank, accumulation tank, accumulation tank with built-in DHW tank and swimming pool. Hydraulic connection of the multiple tanks can be selected via pumps, 3-way zone valve and 2-way zone valve. It is possible to control the pump for heating the first tank with the next one(heating the DHW tank with the accumulation tank). The first tank can be heated by an el. heater (via contactor) and with up to 2 conventional heat sources (it is possible to choose between wood boilers, pellets, oil / gas, el. boiler or heat pumps). The control unit can control the recirculation pump with impulse operation at the set schedule time. By entering the correct flow through the solar collectors and by installing the solar collector backflow sensor, sollar controller calculate total gain energy from solar collectors. If the flow meter is installed, the calculation of the energy will be more accurate.

E= 543 (kWh)

In addition to the upper mentioned, the control unit also has protective functions: solar collector cooling function (via tank), tank cooling function (over solar collector or recirculation), disinfection function (legionela protection) and function pump/valve protection function for blocking protection. On the control unit you can determine the priority of solar heating of a single tank, switch on a tank heating priority test, switch on and off certain tank from the heating, switch on one-time heating with conventional sources, switch on party option for one-time heating extension and switch on the holiday option with which are automatically switch on all protective control unit functions to allow the overheating / freezing of the collector to be minimized. To monitor the operation of the solar system, it is possible to install a WiFi box and through the web portal monitor the individual temperatures and operation of individual pumps and valves. Through the web portal it is also possible to change the set temperatures of the tank and solar collector.

Tank cooling Cooling the tank, ie lowering the water temperature in tanks to prepare the tank for accepting the new solar energy the next day, can be done over the collector or through recirculation (if it is installed in the system and connected to the controller). NOTE: Cooling of the tank always start from the lowest priority to the tank with the highest priority. Tanks must have upper tank sensor. Collectors - Cooling the tank via the collector (and pipes to the collector).

T T T TIP: If you want to cool the tanks to leave more space for solar energy for the next day, it is recommended to enable the Tank Cooling function together with Collector Cooling function and lower the [TMAX tank] down (ca. 50°C). When the tanks are filled up to [TMAX tank] the collectors wil reach the cooling point faster (adjust according to the number of collectors, not to pass TMAX coll), the temperature in the tanks will start to rise up to 90°C, but after that will start tank cooling which will try to cool tanks down to [TMAX tank-dTcoll/tank] (ca. 50-4= 46°C).

NOTE: It is recommended to cool the tank with flat plate collectors (not vaccum tube) because of less insulation on flat plate collectors. Cooling takes place when the temperature in the collectors is lower than the temperature in the tank down [Tcoll. + dTcoll. / tank. T MAX is tank.1] (only runs on the first tank).

With this function we want to delay boiling of the solar fluid in collectors, by raising the temperature in the tanks to the maximum temperature [T MAX tank= 90°C]. The collector cooling function starts if the temperature in the collectors reaches [T MAX collector - d TCooling_collector] and if all tanks are full, to [T MAX tank(set)].

2.x. Frost protection In this menu, you can switch the collector freezing function on or off. Use this function when in the solar water system is water (instead of solar fluid) and if the outer temperatures do not drop below zero. In the solar system it is always recommended to use a mixture of glycol and water (solar antifreeze with water). The frost collector protection function causes the circulation of water through the collectors to prevent the freezing with help of heat energy from the tank. The frost protection drops when the temperature in the collectors falls to the set temperature under PIN code (factory setting + 4°C). The frost protection starts when the temperature in the collectors rises by + 2°C of the set temperature [Tstart] and when the temperature in the tank lower drops down to + 3°C (to prevent freezing of the tank). Frost protection starts from the least priority tank to a tank of higher priority. NOTE: Only use this function when only water is in the collectors. It is never recommended to fill the solar system with water only (without glycol)! By switching on the frost protection function, it is possible to coll the tanks. Possible significant energy consumption of conventional sources in heating tank due to "heating" the collector! Factory settings Frost protection

8.9.5. Last change of glycol Depending on the solar system operation and the recommendation of the glycol manufacturer, the glycol in the solar system must be regularly replaced (due to often glycol overheating (steam in the collectors) glycol ages faster and thickens which lowers the solar collector efficiency and finaly can lead to solar colletor stoppage).The recommendation is to replace glycol every 2 years. After the glycol replacement in the solar installation you need to reset the counter in the menu 8.12.2. Reset glycol counter, by help of which a new time counting of 2 years will start and after which a warning appears for the replacement of glycol in the solar system. NOTE: The warning for the glycol replacement appears after the expiry of 2 years from the last reset of the glycol counter. After the appearance of the warning the solar system continuous normally with the operation, only the warning is active that long until the counter is annulled. The annulment of the counter warning for the glycol replacement can be found in the installation menu -> 8.12.2 Reset glycol counter.

It is possible to configure up to 4 tanks. It is possible to select one of three hydraulic connection. It is possible to select mutual reheating of the first 2 tanks (reheating of the DHW tank with the buffer tank).

8.1.2.1. Tank 1 , type In this menu it is necessary to select the type of the installed tank (1 – 4). Tank 1 must always exist. The types of tanks can be DHW tank, buffer tank (BUF), buffer tank with DHW tank (BUF with DHW) or pool (Pool). Only with the Tank 1 it is possible to configure reheating with conventional sources and the recirculation of DHW. If conventional sources are configured (boiler 1,2 or electric heater), the installation of the upper sensor in the Tank 1 is obligatory. If the upper sensor in the Tank 1 is not installed, the conventional sources cannot be included into the tank reheating. The solar collector pump operates according to the temperature difference of the lower tank sensor and the solar collector sensor. If the pool is configured as a tank, the pool sensor is configured as the upper tank sensor and the solar collector pump operates according to the temeperature difference between the upper tank sensor (pool) and solar collector sensor. The pool must always be configurated only as the last tank (it is not possible to choose it between two tanks), as the tank 1, 2 or 3. The controller can control manage each tank with two sensors – upper and lower (except the pool where only the upper sensor is used) or only with one, lower sensor, but in this case some of the controller functions are disabled. The upper sensor serves for the tank safety and protection functions DHW tank (maximum temperature), for the tank mixing/reheating function and for 2 heat exchangers the tank reheating with conventional sources. 2 temperatures The lower sensor serves for the solar collector tank reheating.

The sensor serves for a more accurate measuring of the collected energy from the solar collectors (with solar collector sensor and correct entered or measured fluid flow through the collectors). If the back flow temperature sensor is not installed, the controller takes as the back flow temperature the lower tank temperature. NOTE: The measuring of energy is done over the temperature in the solar collector sensor, the temperature in the back flow sensor (or lower tank sensor) and entered flow (or flow value from the installed flow meter). The calculation of the collected energy from the solar collectors depends a lot on the accuracy of the measured temperatures and the entered/measured fluid flow through the solar collectors. In case of 2 solar collector fields the back flow sensor is installed on the return of the first field while for the measuring of energy of the second field the lower tank temperature is taken into consideration.

Tank cooling Tank cooling ie. decrease the water temperature in the tanks to prepare them to accept new solar energy next day can be done through collectors or through recirculation (if it’s installed into the system and connected to the controller). NOTE: tank cooling always starts from the tank with the lowest priority to the tank with highest priority. Through collector - cooling the tank through the collector (and pipes to the collector)

T T T

NOTE: it’s recommended that cooling is done through flat collectors (not vacuum tube collectors) due to lower insulation of the flat plate collectors. Tank cooling is done when collector temperature is lower than temperature in tank lower [Tcoll + dTcoll/tank < T MAX tank X]. Tank cooling start only when all tanks are filled to the [T MAX tank] and start from lowest priotiry tank. Tank cooling stops when temperature of the upper tank sensor is lower than the difference collector/tank [Ttank_up < TMAX tank -dTcoll/tank]. Through recirculation - cooling of the first tank through recirculation (cooling only first, priority tank, only if recirculation is connected). Tank cooling starts only when all tanks are filled to the [T MAX tank] and when [Ttank 1_up > T MAX tank 1] (only in first tank).
