Frequently Asked Questions - SPM-2 Warmup
How do I install the Warmup SPM-2 thermostat?
Turn off the power at the circuit breaker, then connect the load wires and floor sensor to the designated terminals. Mount the thermostat in a standard 86 mm wall box and secure the faceplate.
Can the SPM-2 control both underfloor heating and radiators?
The SPM-2 is designed for electric underfloor heating only. It can switch a 16 A resistive load, which covers most floor heating mats and cables but not radiator valves.
How many time periods can I program each day?
The SPM-2 offers 4 time periods per day with independent temperature settings for each period, allowing a customised 7-day schedule.
What is the function of the included floor sensor?
The floor sensor measures the actual floor temperature to provide accurate, comfortable heating and prevent overheating. It also improves energy efficiency by limiting the maximum floor temperature.
Is the SPM-2 compatible with smartphone apps or voice assistants?
The SPM-2 is a standalone programmable thermostat and does not include Wi-Fi or smart home integration. For app control, consider Warmup's smart thermostat models.
How do I reset the thermostat to factory defaults?
Press and hold the power button and the down arrow for 10 seconds until the screen resets. This restores the default schedule and temperature settings.
What do the error codes on the display mean?
The most common codes are E1 for a short-circuited floor sensor and E2 for an open sensor. Check the sensor wiring or replace the sensor if the error persists.
Does the SPM-2 help reduce heating costs?
Yes, the programmable schedule, floor sensor limit and adaptive start ensure the heating runs only when needed, reducing energy waste compared to non-programmable thermostats.
How should I clean and maintain the thermostat?
Clean the exterior with a soft dry cloth. Never use water, solvents or abrasive cleaners, and do not spray water directly on the device.
What warranty period applies to the SPM-2?
Warmup provides a 5-year warranty covering manufacturing defects when the thermostat is installed according to the user manual. Keep the receipt as proof of purchase.
