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.
