• Leave the existing sensor in place .
• Install new sensor on the relevant pipe, BT3 on XL2 (Climate system return) and
BT12 on XL1 (Climate system supply) right above the spit box .
• Ensure good contact between sensor and pipe and good insulation .
• Guide the sensor cable to the control board by use of a spare cable gland (UB1, UB2
