Product Information

The RX1-S V2 RF Receiver & Boiler Relay is a radio equipment type TPOne -RF + RX1-S V2 that is compliant with directive 1999/5/EC. The product is manufactured by Danfoss A/S and can be used for controlling heating systems.

Installation Guide
The user guide for the product can be downloaded from heating.danfoss.com. Below are the installation steps for the product:

The installation should be done by an authorized electrician.
Install the room thermostat at approximately 1.5 meters above the floor and avoid placing it in direct sunlight, draught or other heat sources such as TV’s.
Decide on the location of the RX1-S V2 receiver ensuring a minimum space of 30cm from the boiler housing. There must be no large metal objects such as boiler cases or other large appliances in line of sight between the thermostat and the receiver as this will prevent RF communication.
Remove and mount the RX1-S V2 backplate directly to the wall or on a wall box and wire it as required for application.
Locate hooks at the top of RX1-S V2 into the top of the backplate and lower it into position and tighten the retaining screw. Switch on mains power to start RF pairing.
Loosen the lower retaining screw of the thermostat and carefully remove the backplate.
Insert 2x AA Alkaline batteries to front part taking care to insert correctly as indicated. Check RF connection between the thermostat and RX1-S V2 receiver before fixing it in its final position.
Mount the backplate directly to the wall or on a wall box. The backplate included within the product packaging must be used forinstallation.
Locate hooks at the top of the front part into the top of the backplate and lower it into position and tighten the retaining screw.

Dimensions and Wiring
Refer to fig. 4 for dimensions and fig. 5 for wiring diagram on page 45.

RF Pairing
The following are the steps to pair the RX1-S V2 receiver and thermostat:

Ensure power to RX1-S V2 receiver is switched on and batteries are inserted into the thermostat.
Put the thermostat in pairing mode, see thermostat installation guide.
Press both PROG and CH buttons on RX1-S V2 until button LEDs flash.
If pairing is successful RF icon on thermostat will stop flashing and remain on.
If pairing is not successful try moving thermostat to an alternative position and retry.

Legacy – RF Pairing
Use this guide when replacing the RF receiver only, where existing room thermostat is reused. If both products are changed follow normal pairing procedure, see 3.1 RF Pairing, page 5.

Ensure the power to RX1-S V2 receiver is switched on and batteries are inserted into the thermostat.
