Location, Fig. 1
Do not site the room thermostat in a draught, in
direct sunlight or close to appliances giving off
heat (e.g. television set.)
Fixing, Fig 2 and 3
Make sure the supply voltage to the system is
disconnected before commencing installation
or subsequentially removing the thermostat
cover.
Fix the base moulding on a flush box. The
temperature range can be limited by moving
the two springs on the back of the setting dial,
Fig 4.
Wiring, Fig 5, 6 and 7
Switch function: SPDT, Fig 8
230 V, 50 - 60 Hz, 10 (4) A
Min. contact load: 150 mA
Note: Always connect the live (L) to terminal .
When the room thermostat is connected to an
inductive load, without noise suppression, there
might be risk of radio and TV interference.
RMT versions with parallel accelerator Rp, will
have a lower temperature differential when
terminal  is connected as shown in Fig. 6 and
7.
RMT-230T only
RMT-230T will set back the temperature by 5K,
when the built-in resistance Rn is connected as
shown in Fig. 7.
Note:
A means of disconnecting the supply with a
contact separation of at least 3mm in all poles
must be incorporated in the fixed wiring,
according to BS 3955. This product does not
require an earth connection.

Summary

Location

Choosing the Installation Location

Select a location away from drafts, direct sunlight, or heat-emitting appliances like televisions.

Fixing and Mounting

Installation Procedure

Disconnect power before removing the cover. Fix the base to a flush box, limiting the temperature range with springs.

Wiring Connections

Electrical Specifications

Details switch function (SPDT), voltage (230V), frequency (50-60Hz), and current rating (10(4)A, 150mA min).

Live Connection

Critical note: Always connect the live (L) wire to terminal 0.

RMT Versions with Rp

RMT models with parallel accelerator Rp offer lower differential when terminal 4 is connected as shown.

RMT-230 T Night Setback

The RMT-230T model reduces temperature by 5K when the built-in resistance Rn is connected.
