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.

4 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.

Only when the cylinder is installed will this wiring be needed. The unit only sends an on/off 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 fixed 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. Control port signal type Voltage Maximum running current (A) Wiring size(mm2) Type 2 220-240 V AC 0.2 0.75 Note: The heat pump unit only sends an ON/OFF signal to the immersion backup heater. The power source for the heater must be supplied from a fused spur. Baxi HP40/HP50 Monobloc Heat Pumps
