This couple (thermostat BT-x02 or BT-x03 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 and BT-DP02 RF it is possible to configure the receiver in manual mode, heating mode, cooling
mode or automatic mode (Please refer to the BT-Dx02 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.

live contact. (Available with all thermostats of the BT-x02 BT-x03 range)
 The cooling relay is used to manage an actuator for a cold water circuit. (Not available
