Specification scope: These values refer to the wired NORA HT25 only. RF and SMART versions have separate receiver, power and connectivity requirements. The manufacturer’s 0.1°C measurement figure is reproduced as reported; it is not an independently established ±0.1°C accuracy claim. Check the current manual and exact variant before installation.

NORA HT25 — engineering and installation notes

Physical fit and supply: The linked model sheet records 85.7mm / 85.7mm / 33.5mm and 3V DC (2 x AAA Alkaline Battery). Check the wall plate, cable entry, sensing location, battery access and space for the NORA HT25 enclosure before substitution.

Heat source interface: The stated relay rating is 2A/30VDC (Resistive Load) 0.5A/125VAC (Resistive Load). This manufacturer resistive-load value cannot establish suitability for all boiler control inputs or inductive loads; compare terminal voltage, open/close logic, isolation and load type with the receiver appliance’s wiring diagram.

Room control: Recorded setpoint limits are (5°C) – (30°C) and operating sensitivity is (-2.0°C) – (+2.0°C). A sensitivity configuration range must not be advertised as temperature-measurement accuracy. Validate switching behavior, heat source cycling and the building’s thermal response during commissioning.

Product identity: The NORA HT25 wired card does not establish the mains receiver, wireless link or app features of an RF/SMART version, even if manufacturer families share an aesthetic. Use current General Life installation documentation for the ordered suffix.
