Page 17: Connection Of The Sensor
5.7.1 Connection of the sensor Step 1: Access the sensor mounting plate. To do this remove the twin thermostat box (A) by removing the screws in the 4 corners only and insulation foam (B) to access the sensor mounting plate (C). Remove the M5 fixing screws. Step 2: The sensor mounting plate will have two vacant slots for additional sensors (D). - Page 18 Step 3: Fit two M5 fixing screws into the cylinder bracket (F). Slide the sensor mounting plate behind the M5 fixing screws (G). Step 4: Insert two remaining M5 screws (H). Tighten the screws until the thermostat bulbs and heat pump sensor are held firmly against the wall of the inner cylinder. Note: there should be no movement in the phials (four clips in the centre of the sensor mounting plate) that are used to hold the bulbs and sensor.
