Thermostat frequently loses connection to receiver; heating cuts in and out unpredictably.

Safety first: Only low-risk adjustments are needed; mains wiring changes should be done with power off.

Steps to check:

• Improve placement: Move the thermostat or receiver to reduce the number of walls and metal objects between them. Avoid mounting the receiver inside metal enclosures.
• Replace batteries: Fit fresh batteries in the thermostat to ensure strong RF transmission.
• Reduce interference: Keep the receiver away from Wi-Fi routers, cordless phone bases, and other RF devices. Change channels on nearby devices if possible.
• Re-pair devices: Clear and re-establish the RF link between thermostat and receiver following the Salus instructions.

Resolution: If intermittent communication persists at close range, replace the thermostat or receiver RF module.
