Remote Electronic Room Thermostat with Radio
Frequency Communication (Independently Surface Mounted)
USER INSTRUCTIONS
RT2-RF NIGHT SETBACK FEATURE
The RT2 incorporates an easy to use, manually selected night setback
feature which allows the user to put the thermostat into setback mode.
The setback feature self cancels at a time programmed in by the user.
SETTING UP AND USING THE THERMOSTAT
1. Slide the battery cover to the left to reveal
the batteries. Remove the paper insulator
from between the batteries and the battery
contacts. The blank display will change to
show actual temperature in the large
characters and required temperature in the
smaller characters. Fig 1 shows a typical
display where the actual room temperature is 21°C and the required
temperature is 20°C. Note the "d" symbol on the left hand side of
the display which signifies that the thermostat is in normal "Day"
mode.
2. Press the PROG key - the display changes
to show Time (Fig 2). Use the
s
and
t
keys to set the display to the current time of
day.
3. Press PROG a second time. The display
changes to that shown in Fig 2. Use the
s
or
t
buttons to adjust the time at which the
set-back is to be cancelled. Once selected,
this time applies to each day.
Note:
This time setting can be adjusted at
any time by repeating steps 2-3 above.
4.
IMPORTANT:
Press PROG for a third time to return the thermostat
to the run mode before using the
s
and
t
button to adjust the
daytime set temperature to the required level. This can be adjusted
between 30°C and 5°C. Please note that the thermostat can also
be set to "Off", should this be required.
5. If the room temperature drops below the selected temperature, a
flame symbol will light to indicate that the thermostat has switched
on.
6. The thermostat will control at the selected set temperature until
the settings are changed or set-back mode is selected.
SELECTING SETBACK MODE
7. To select setback mode, press both
s
and
t
buttons together. The display will change
to show actual temperature and set-back
temperature. An "n" symbol is also lit to
signify that the thermostat is now in set-
back mode. Fig 3 shows a typical display.
8. Use the
s
and
t
buttons to adjust the setback temperature to
the required value. This can be adjusted between 30°C and 5°C.
Please note that the thermostat can also be set to "Off", should
this be required.
Note:
This setback temperature value will be used every time the
thermostat is put into set-back mode unless it is altered at any
time when the thermostat is in setback mode.
9. If the room temperature drops to below the selected setback
temperature, a flame symbol will light to indicate that the thermostat
has switched on.
CANCELLING THE SET-BACK MODE
10. The setback mode will cancel automatically the next day at the
time set in section 3 above. The setback can also be cancelled
manually at any time by pressing both the
s
and
t
buttons
together for a second time.
ESTABLISHING COMMUNICATION BETWEEN THE RT2-RF
THERMOSTAT AND ITS RX1 RECEIVER MODULE
Once the programming has been completed, communication between
the thermostat and the receiver module has to be established.
SINGLE ZONE SYSTEM WITH RX1 RECEIVER
1 - Press and hold the
t
and + buttons of the RT2-RF for at least 3
seconds. The thermostat will now transmit a continuous signal which
contains its unique identity for a period of 5 minutes.
2 - Within the 5 minute period go to the RX1 receiver module and press
both "PROG" and "CH1" buttons together and hold for at least 3
seconds, then release.
During this process the RX1 receiver will have learnt the unique
transmission code of the thermostat and will in future react to all
transmissions from that thermostat.
To stop the continuous transmission on the RT2-RF unit press the
s
button.
TWO ZONE SYSTEM WITH RX2 RECEIVER
1 - Repeat as above for zone one (CH1).
2 - Repeat steps one and two above for zone two, remembering to
press "PROG" and "CH2" on the RX2 receiver.
THREE ZONE SYSTEM WITH RX3 RECEIVER
1 - Repeat as above for zones 1 and 2 (CH1 and CH2).
2 - Repeat as above for zone 3, remembering to press "PROG" and
"CH3" on the RX3 receiver.
BATTERY REPLACEMENT
When the batteries approach the end of their life a battery symbol will
flash on the left hand side of the display (see fig 5). When this symbol
appears both batteries should be replaced with high quality alkaline
cells. Having replaced the batteries the required temperature should
be re-set using the
s
and
t
keys.
