Important
A temperature sensor and T5 adaptor (part no. 7750595) are required to enable the kit to operate correctly and to
connect the sensor to the PCB. One each of the sensor and T5 adaptor are supplied with the heat pump. If these are
already being used for another of the products functions please order part no. 7750595.
Fig. 1: Hydraulic Schematic.
Warning
The schematics below are based on the Baxi HP40/HP50 Monobloc Heat Pump range. See manufacturers
instructions on how to connect the cylinder wiring to other heat pumps to ensure shut down of all heat sources in
the event of a thermal cut out on the cylinder.

Notes: DHW sensor connection:
1. Identify the output from the heat pump - CN13 on PCB “A” Main Control Board Hydraulic.
2. Route the domestic hot water sensor cable via the low voltage cable feedthrough on the heat pump.
3. Fit the sensor connector onto the T5 adaptor.
4. Insert the sensor into the overheat thermostat pocket.
Notes: Diverter valve connection:
1. Identify the output from the heat pump - CN11 connections 5 & 6 (N=16) on PCB “A” Main Control Board Hydraulic.
2. Route the valve power cable via the high voltage cable feedthrough on the heat pump.
3. Connect the valve power cable to PCB “A” Main Control Board Hydraulic.

Power supply

Connection of the immersion backup heater cable
depends on the application. Only when the cylinder is
installed will this wiring be needed. The unit only sends
an on/o signal to the backup heater. An additional
contactor is supplied and a dedicated terminal is needed
to supply power to the backup heater.
The 25 A contactor supplied with the cylinder is ONLY
suitable for switching the 3 kW immersion heater in the
cylinder. Ensure that the cable is xed and the strain
relief is used.
Procedure
• Connect the cable to the appropriate terminals as
shown to connections 13 and 16.
• To prevent strain on the cable secure it with cable
ties to the cable tie mountings.
