The BT-WR02 H&C RF receiver is a Wall mounting receiver, specially designed to control hydraulic
heating regulation or cooling regulation.
It embeds a proportional regulation with a time cycle of 10mn and an Hysteresis regulation:
- The heating relay is used to control a boiler in free contact or a valve or an electric radiator in live
contact. (Available with all thermostats of the BT-XX02 RF or BT-XX03 RF range).
- The cooling relay is used to manage an actuator for a cold water circuit. (Not available with BT-
A02 RF thermostats).
This couple (thermostat BT-XX02 or BT-XX03 and receiver BT-WR02 H&C RF) can also be managed by a Central unit BT-CT02
RF to have a full control of your heating installation from one point. In that case, the receiver works always in automatic regulation
mode for the heating/cooling switch. With the central unit, it is possible to pair the receiver in “Regulation/heating” mode and in
“Hydraulic circuit” mode. It is not possible to pair the receiver in lighting mode or ON/OFF mode.
You can access to the general leaflet of the system on wattswater.eu.
With a BT-D02 RF/BT-D03 RF or BT-DP02 RF/BT-DP03 RF it is possible to configure the receiver in manual mode, heating
mode, cooling mode or automatic mode (Please refer to the BT-XX02 RF or BT-XX03 RF leaflets).
In all cases, the receiver is making cooling only in comfort mode. All other modes (Reduced, anti-freeze, auto in Reduced) forbid
the cooling regulation.
In case of set point modification, a delay of 5mn is always applied before switching from cooling to heating or heating to cooling.
In automatic regulation, a dead band of ± 1°K with timer is applied before switching from heating to cooling or from cooling to
heating.

The receiver is delivered with 2 outputs in free contact mode. To trigger the outputs in live contact, linked the live on 1 point of
each connector using the cable supplied in the box.
