3.4 Heating water temperature, return to condenser
The buffer tank sensor (TE255) and the heating water return sensor (TE201) share
the same sensor input (B2) and terminal on the terminal block (X3:2). Only one of
the sensors can be connected to the terminal block at a time. The unit comes with
the buffer tank sensor connected, which means that condenser return temperature
measurement is disabled by default.
The unit has a built-in condenser return temperature sensor (TE201), but the sensor
is not connected to the switchboard. The sensor can be connected to the terminals
occupied by the heating circuit flow sensor (TE212) or the DHW sensor (TE266),
provided that one of these is not in use. Additionally, the number of free sensor
inputs can be increased by installing an auxiliary controller (available as an optional
accessory).
3.5 Heating circuit’s control valve
The heat pump can control both 230-V 3–point control valves and 0–10-V (24 V)
control valves. See the instructions for connecting the control valve actuator to the heat
pump in the unit’s electric diagram.
The control outputs for both valve types are enabled by default (and are simultaneously
active), so there is no need to activate them. The position of the valve is indicated in
the piping diagram. For the heat pump to be able to automatically regulate the valve,
the heating circuit needs to be equipped with a flow temperature sensor.
Control valves are available as optional accessories (see section Accessories ).
Valve and actuator Installation
Below is a general description of how to install an Esbe VRG130 series control valve
and the associated Esbe ARA600 series actuator. Other valves are installed in a similar
way. For more detailed instructions, please refer to the guide delivered with the valve
and actuator.
