Ideal Heat Meter Temperature Sensor 130mm 177635

The Ideal heat meter temperature sensor, part 177635, is a probe-type temperature sensor used on Ideal heat interface units (HIU). It monitors water temperature within the heat meter circuit so the unit can register flow and return conditions accurately. The probe measures 130mm in length and is listed under the reference SATKF010.

• Heat meter readings drift or fail to match the temperatures recorded elsewhere on the system
• The HIU reports implausible flow or return temperatures, or drops the temperature reading altogether
• Metering or billing figures become inconsistent between the HIU display and the heat meter
• The probe or its lead is physically damaged, corroded or wet at the connection point
• Fault codes or lockouts on the HIU that clear when the sensor circuit is checked

• Confirm the appliance model and serial number against the compatibility list, as sensor fitment varies between Ideal Commercial units
• Check the existing probe length is 130mm before removing it, so the replacement seats correctly in the pocket
• Note the alternative part number 1783143 when cross-referencing older documentation or stock records
