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.
