RF Thermostat
(Continued)
MANUAL MODE - THERMOSTAT (Continued)
The Room Fan speed settings are as follows:
-
Speed 1 – difference between room temp. and set temp. is 0-1°C e.g. room 20.5°C – set 21°C
-
Speed 2 – difference between room temp. and set temp. is 1-2°C e.g. room 21°C – set 22°C
-
Speed 3 – difference between room temp. and set temp. is 2-3°C e.g. room 22°C – set 24°C
As the Room temperature increases or decreases, the Flame level will change according to the difference between this
and the set temperature. e.g.
-
Flame will be on Low when room temp. at 20.5°C and set temp. at 21°C
-
Flame will be on high when room temp. at 21°C and set temp. at 24°C
-
Flame will adjust to the appropriate level between these two settings when temperature difference is within this
range.
If the Room temperature rises 1°C above the Set temperature, the Flame will be switched off.
If the Flame is off and the Room temperature drops down to the Set temperature or below, the heater will initiate the
start up sequence and the Flame will be switched on again.
Whenever the Flame is on and at any level, and the Thermostat sends an OFF command, the Flame will be switched off.
The Room Fan however will continue to run at the Low fan speed until the outlet temperature drops below 40°C and
then switch off.
The flame height and fan speed are not manually adjustable. The flame height and fan speed are set by the thermostat
according to the difference between the set temperature and the room temperature.
Note: the flame can be off, or has 7 graduated settings. The fan has 3 graduated settings.
AUTOMATIC MODE - THERMOSTAT
The automatic mode allows the RF Thermostat to control the Flame and Fan according to the programmed times and
temperatures. The switch on and off sequences operate as per Manual operation detailed above.
With the thermostat on, press and release the <A/M> button until the word AUTO appears on the LCD.
–
To correctly operate in automatic mode, the time and day of the week must be set.
–
The thermostat will now operate according to the program set for the current time period. Programming
instructions are found on page 17.
Manually overriding the set program
At any time, the temperature or fan speed may be adjusted up or down similarly to operating in manual mode. However,
whenever the thermostat changes to a new time period, the temperature will be set automatically according to that
period’s setting.
As a safety feature, if the Room temperature goes above the Set temperature, the Flame will switch off but the Room fan
will continue operating on speed 1 for a further 3 minutes.
