FAQs

How do I set the temperature?

Simply turn the dial to your desired temperature. The digital display will show the selected temperature between 5°C and 30°C.

What type of batteries does it use?

It uses 2x AA Alkaline batteries (1.5V).

How long do the batteries last?

The batteries provide a power reserve of approximately one year under normal operation.

Can this thermostat be used with a combination boiler?

Yes, the Sangamo Choice Rstat3 features volt-free contacts, making it suitable for systems with either a combination or a normal boiler.

What if I have a three-wire installation?

For three-wire systems, you will need to cut back and make safe the neutral wire, ensuring only the two required wires are connected to the thermostat.

How do I switch between comfort and economy modes?

The thermostat automatically adjusts between comfort and economy based on the temperature setting. A lower dial setting typically corresponds to an economy mode, while a higher setting is for comfort.

Is this a programmable thermostat?

No, the Sangamo Choice Rstat3 is a non-programmable digital thermostat. It offers simple, manual control with a digital display.

Troubleshooting

Thermostat not turning on heating

Check that the batteries are correctly inserted and have sufficient charge. Verify the room temperature is below the set point. Ensure wiring connections are secure and correct for your system type.

Heating stays on constantly

Confirm the room temperature is actually below the set point. Check wiring connections. If the issue persists, there may be a fault with the thermostat or the heating system itself.

Digital display is blank

Replace the AA batteries. Ensure batteries are inserted with the correct polarity.

Inaccurate temperature readings

Ensure the thermostat is not located near heat sources (radiators, direct sunlight) or drafts, which can affect its sensor. Allow the thermostat time to acclimate to the room temperature after installation or battery change.

Setup, Compatibility & Care

Setup:

Care:

  • Clean the thermostat periodically with a soft, dry cloth. Avoid using abrasive cleaners or solvents.
  • Replace batteries when indicated or annually to maintain the one-year power reserve.
  • Ensure the thermostat is not obstructed by curtains or furniture, as this can affect temperature sensing.
