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.

(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.
