Define Heat Pump 1 Menu
(Installer/Define application/Def Heat pump 1)
Heat pump 05
Here you select if heat pump 1 (05) is included in the operation.
The factory setting is “No”. When the setting is “Yes”, the menu lines are shown
underneath. These are turned off at the setting “No”.
It is important to note that the setting locally in heat pump 1 (05) should be “A”,
if a heat pump is installed in the system. If there is more than one heat pump in
the system, heat pump 1 should be locally set to “A1”.
Thus, this setting is made in the heat pump’s own control.
Type
The type of heat pump is selected here. “EcoAir” or ”EcoPart”.
Charge Pump 31
Here you set the type of charge pump. “0-10V” is for a speed-controlled circulating
pump and “relay” for a pump with fixed speed setting.
3-way valve 54

pump-heated radiator water to either CTC EcoZenith
I
550’s upper or lower tank.
3-way valve 55
Indication that 3-way valve (55) is activated. This 3-way valve retrieves radiator
water from either CTC EcoZenith
