ELECTRONIC COMPONENTS

This section details the method for troubleshooting the non-standard electronic

components on the boiler including the electronic water pressure sensor and the

temperature sensors.

5.2.1 Temperature Sensors

The resistance of the temperature sensors varies inversely with temperature. To

test, measure the temperature of the sensed environment and compare with the

value derived from the measurement of the resistance (obtained by connecting a

good quality test meter capable of measuring up to 5,000 kΩ (5,000,000Ω) at the

controller end of the sensor lead).
To obtain a resistance reading, remove power to the boiler. For the supply water

and return water temperature sensors, remove the wire leads by disconnecting

their respective Molex connectors. Place multi-meter probes into sensor’s male

Molex connector socket. Do not apply voltage to the sensor (damage may result).

12KΩ Temperature Sensors supplied with boiler. See Table 12 for resistance

values.
