FAQs
How do I set the desired temperature?
Simply turn the rotary dial to your preferred temperature setting. The selected temperature will be displayed on the LCD screen.
What type of batteries does the ESRTD2 use?
The ESRTD2 typically uses standard AA or AAA batteries. Please refer to your user manual for the exact battery type and number required.
What does the flame symbol on the display mean?
The flame symbol indicates that your heating system is currently active and working to reach the set temperature. When the symbol is not visible, the heating system is inactive.
Can this thermostat be used with electric underfloor heating?
The ESRTD2 is generally designed for central heating systems (like boilers) with volt-free contacts. Compatibility with electric underfloor heating depends on the specific system's wiring and voltage requirements. Please consult your underfloor heating system's manual or a qualified installer.
How do I know if my heating system is compatible?
The ESRTD2 is compatible with most 24V-230V heating systems that have volt-free terminals for a thermostat. If your existing thermostat uses two wires and your boiler has a dedicated thermostat connection, it is likely compatible. Consult your boiler's manual or a professional installer for confirmation.
Does this thermostat have a programmable schedule?
No, the ESI ESRTD2 is a non-programmable electronic room thermostat. It allows for manual temperature setting via the rotary dial.
Troubleshooting
Thermostat display is blank.
Check and replace the batteries. Ensure they are inserted correctly according to the polarity markings.
Heating system does not turn on.
Verify that the thermostat is receiving power. Ensure the wiring connections are secure and correct for your system. Check that the set temperature is higher than the current room temperature. Confirm the flame symbol is displayed when calling for heat.
Heating system runs constantly.
Ensure the set temperature is not excessively high. Check wiring connections for any shorts or incorrect routing. If the issue persists, consult a qualified heating engineer.
Inaccurate temperature readings.
Ensure the thermostat is not located near a heat source (e.g., direct sunlight, radiators, drafts). Allow the thermostat some time to acclimate to the room's ambient temperature after installation or battery change.
