Warmup DWS300, Installation Manual

Page: 5 / 21

Install the RCD
The electrician must install a dedicated RCD or use an existing RCD. The electrician may wish
to use a combination ‘double pole switched’ fused-spur/RCD. No more than 4.8kW of
heating may be connected to each 30 milliamp RCD. For larger loads, use multiple RCD’s.
Note: It is possible to run the heater(s) from an existing circuit. The electrician will be able to determine whether or
not the circuit can handle the load and if it is RCD protected.
Install electrical boxes and trunking
You will require a deep (35mm) back box for the Warmup
®
Thermostat. If you are installing
more than two heaters, a junction box will also be necessary. The wiring to the thermostat
should be chased into the wall and protected by conduit or plastic trunking.
Connecting the Warmup ® Thermostat
The thermostat should be connected to the main electrical supply via a fuse or circuit
breaker, ‘double pole isolator’ in accordance with the wiring regulations.
The thermostat should be installed within the rooms or area to be heated. In the case
of bathroom installations, electrical regulations prohibit the installation of the thermostat
within the bathroom itself. In such cases, the thermostat should be fitted to the outside
of an internal wall of the bathroom, as close to the undertile heating as possible, for example
in an adjacent airing cupboard.
Note:
The floor probe wire can be
extended up to 50m.
