V.a.16) Scheme 16/17
Installation 15/17 Operates:
 The Collector Pump.
 The Switching Valve.
 The Accumulation Tank - Solar.
 One direction of the collectors' location.
 Additional peripherals.
Installation Sensors:
 The collector's sensor.
 The two sensors of the Accumulation Tank.
 Valve sensor.
This installation allows the user to control the valve of the
CH installation return to the accumulation tank. The valve
switches the circulation from the top part of the tank to the bottom part.
Additional parameters to be adjusted:
 Valve delta.
V.a.17) Scheme 17/17
Installation 17/17 Operates:
 The Collector Pump.
 The Pump Tank – Receiver.
 The Accumulation Tank - Solar.
 Heat Receiver.
 One direction of the collectors' location.
 Additional peripherals.
Installation Sensors:
 The collector's sensor.
 The two sensors of the Accumulation Tank.
 Heat Receiver sensor.
Additional Parameters to be Adjusted (additional submenu in the service menu):
 Heat Receiver: receiver maximum temperature, receiver activation temperature, heat receiver
hysteresis.
V.b) Accumulation Tank
This menu allows the user to adjust all parameters related to the tank (heat container).
V.b.1) Set Temperature
This function is used to adjust the set temperature in the container which leads to the deactivation of
the Collector Pump.
V.b.2) Maximum Temperature of Tank 1
Using this option, the user may declare the maximum acceptable safe temperature value to which the
tank is allowed to heat in the case of
Collector Overheat .
If the collector reaches its alarm temperature ( Overheat ), the pump is activated automatically
in order to cool down the heated collector, regardless of the set temperature. The pump operates until
reaching
the Tank's Maximum Temperature or until the collector's temperature drops by the value of
the Alarm Hysteresis (see: SERVICE MENU > Solar Collector> Alarm Hysteresis )
V.b.3) Minimum Temperature of Tank 1
Using this parameter, the user may declare the minimum acceptable temperature value to which the
tank is allowed to cool. Below this temperature, the pump does not activate in the Collector Defrosting
mode.
