hot Water sensor
The domestic hot water sensor is an optional accessory and
only functionally-relevant for a separate domestic hot water
tank. You may only use domestic hot water sensors which
have been approved by the manufacturer of the heat pump.
ATTENTION
The domestic hot water tank must be lled before
connecting the domestic hot water sensor to the
heating and heat pump regulator.
If not already prepared at the factory, mount the domestic
hot water sensor (Ø = 6 mm) on the halfway level of the
domestic hot water tank – and always above the internal
heat exchanger of the domestic hot water tank.

(heat pump circuit)
3 Circulation pump from the separation storage
tank (heating circuit)
4 External return sensor (Ø = 6 mm)
ZUP Charging loop, heat pump
HUP Discharging loop, heating circuit
Connect the return ow sensor coming from the isolating
tank to the circuit board of the heating and heat pump reg-
ulator.
