Shock Hazard
This unit must be installed by a competent person,
in accordance with BS 7671 (the IEE Wiring
Regulations), or other relevant national regulations
and codes of good practice.
Always isolate the AC Mains supply before removing
the unit from the Industry Standard Back Plate.
INTRODUCTION
This thermostat can replace most common
residential thermostat and is designed to be used
with electric, gas or oil heating control system or
cooling system.
Unlike ordinary single unit design thermostat,
This unit is a new type of thermostat separating the
thermostat function into two units. The Receiver
serves for wiring connections and heat/cool on/off
control. The Control Centre serves as user interface
and temperature sensing/control. The two units are
linked by RF.
The advantage is that user can put the Control
Centre nearby and can read/control the temperature
of really the living area.
Outlook of Control Centre:
LCD :
Receiver installed on wall box
LED IndicatorsPower switch
Front CoverFront View
ON
OFF
Features :
Several useful function and operating modes have
been incorporated to suit a variety of customer
needs besides all the features associated with the
state of the art programmable thermostat.
Control Centre:
- Can be placed anywhere in the home to detect
and control the temperature of an area of the
user’s choice. Not limited by power control wiring
locations.
- Link with the Receiver via RF. Control distance
100M open site
- LCD shows the "need to know" information
only, which is more easy to understand.
- Real time clock with day of the week display
- Room temperature display
- Control profile display
- Simplified temperature adjustment - Simplified
programming procedure
- 6 pre-defined control profiles, 3 user
programmable control profile
- A protection against freezing
- Temporary override set-temperature
- User selectable temperature span
- User selectable heater/cooler operation mode
- Battery level detection
- 2 AA size alkaline batteries (not included)
- Slim housing design
- EL backlight
Receiver:
- Linked with Control Centre via RF.
- Power control rating up to 230VAC 16A
resistive.
- Powered by line voltage only. No battery
required.
- Two LED indicators for power and output status.
INSTALLATION OF RECEIVER
Caution :
1. The appliance can only be mounted indoors
and in areas free from any water or moisture
2. A suitable fuse with a rating not exceeding
13A, should be in the power line.
3. Observe the nation regulator for the wiring.
4. A qualified electrician is recommended for
installation and servicing.
This thermostat has been designed for simple and
quick installation requiring only a few tools. Only the
Power Control Unit needs to be installed.
Required Tools
• Hammer • Masking tape • Screwdriver
• Drill and 3/16" drill bit (if not installed on a
junction box)
RF Address Code Setting
If there is another user nearby, e.g. in the next
house, your receiver may be fault triggered by their
transmitter. You may select a different RF address
code to prevent this. Receiver can only response to
RF coding with the same address code setting as its
own address code.
1. To adjust address code of Receiver, simply
push up one or more of the 5 dip switch
levers.
2. To adjust address code of Control Centre, open
the housing of the transmitter unit. See battery
replacement section on how to open the housing.
3. Remove one or more of the jumper caps as
shown in the diagram below.
Caution :
1. Address code of Control Centre must be the
same as address code of Receiver. For any
jumper cap removal of address code # in
Control Centre, the same address code # of
Receiver must be put to the UP position.
2. Disconnect AC power and remove batteries
prior to adjusting address code.
Remove one or more of
the jumper cap to adjust
RF address code.
Address code # 1 - 5, from
left to right
Push up one or
more of the
white levers to
adjust Receiver
address code.
Address code # 1
- 5, from left to
right.
Removing your old thermostat
CAUTION : to avoid electric shock, isolate the power
of the heating/cooling system at the main power box
in your home. Read the following instructions careful-
ly before disconnecting the wires.
1. Turn off your old thermostat.
2. Remove the cover from the old thermostat.
3. Unscrew the old thermostat from the wall plate.
4. Now find the screws attaching the wall plate to
the wall, and remove them. You should now be
able to pull the wall plate a small distance from
the wall. Do not disconnect any wire yet, simply
locate the wires.
WARNING:
After removing the wall plate, if you
find that it is mounted on a junction box (e.g. a box
similar to one behind a light switch or electric
outlet), high voltage circuit may be present and
there is a danger of electric shock. Please consult a
qualified electrician.
