Thermostat frequently loses wireless connection to the receiver; heating drops out intermittently.

Safety first: Battery changes are low risk; isolate mains before moving receivers.

• Replace batteries: Fit fresh alkaline batteries in the thermostat to ensure maximum RF output.
• Relocate thermostat: Move the thermostat away from metal objects, large mirrors, or appliances. Avoid mounting on or near metal back boxes without plastic spacers.
• Relocate receiver: If possible, move the Drayton receiver or Heat HubR to a more central, open location.
• Reduce interference: Keep Wi‑Fi routers, cordless phone bases, and baby monitors away from the receiver and thermostat.
• Re-pair devices: Perform a fresh pairing between thermostat and receiver following Drayton’s procedure.
