Settings presents in both views
Pump
● Used: there is a pump in the circuit on the cold or warm side.
● Speed controlled: if the button is active, the pump is a speed-controlled (VFD)
pump. If the button is not active, the circuit has an on/off pump instead.
The drop-down menu allows you to select the control method for the pump. The menu
includes the following options:
● Temperature out: outlet temperature will be used as the setpoint
● Temperature difference: temperature difference will be used as the setpoint
● Constant speed: the pump will run at constant speed
● Temperature out, always on: outlet temperature will be used as the setpoint, and
the pump will run even if the heat pump is off.
● Temperature difference, always on: temperature difference will be used as the
setpoint, and the pump will run even if the heat pump is off.
● Constant speed, always on: the pump will run at constant speed, and the pump will
run even if the heat pump is off.
Valve
● Used: there is a valve in the circuit on the cold or warm side.
● On/Off: the valve can be either fully open or fully closed; otherwise, the valve is a
flow control valve.
● Shared: the valve is shared between two or more heat pumps.
● Control: the valve can be controlled based on inlet temperature or outlet
temperature.
Temperature in, Temperature out
The relevant circuit can be controlled based on either the heat pump inlet temperature
or outlet temperature.
