GENERAL INFORMATION - Introduction & Specification
FD18002 & 18003 Programmable thermostat (Heating & Floor-heating)
Introduction
This Surface-mount programmable thermostat can be used for:
1.
Room-temperature-control thermostat (The room-sensor controls the heating.)
2.
Floor-temperature-control thermostat (The floor-sensor controls the heating, the
room-sensor for room temperature indication).
The thermostat will automatically choose the operation mode. When both room-
sensor and floor-sensor are connected to thermostat, it will operate the mode of
Floor-temperature-control thermostat if only the room-sensor is connected, it will
operate the mode of Room-temperature-control thermostat,
Its programming design is to operate the temperature- control with two setpoints
(
Economy & Comfort) and to spread one day into 48 programming zones.
Users can select the required setpoint to operate the temperature-control in each
of the programming-zone of a day and any day of the week.
A switch ( ) is built on the front panel to enable users to manually turn the unit
ON or OFF.
5
°C Anti-frost protection will be automatically activated after the thermostat is
manually turned off.

1.
Open the thermostat 2. Battery replacement 3.Choosing location for installing
the thermostat
Open the plastic housing is required for installation
(
Flat-head & “+ head” are required as assisting tools)
How to open top housing
Fitting/Replacing the Battery
Choosing correct location for the thermostat
For obtaining thermostat’s best performance upon using, recommend user to
follow up with precaution listed below.
(1).
Place thermostat on wall
inside the room approximate 1.5
meters above floor.
(2).
Avoid position where
temperature sensing easily
interfered by ambience, such as,
directly exposed to Sun-Light,
too near to any Heat-Generate
devices /refrigerator, right next to
entrance/exit/window, etc.
(3).
Prevent thermostat from installed at position that furniture may interfere
1.
Using hands
to take off
the front
CAP.
3.
Insert the flat-
head
screw-driver at
position shown
in picture.
2.
To slacken the
fastening screw
with “+ head”
screw-driver.
4.
Tilt it to the direction
as shown in picture
to separate the top
housing from
the bottom housing.
The Battery compartment is situated underneath the
front “CAP”. Slide the cover off the battery-com-
partment for battery replacement.
Requires 2 pieces of AA 1.5V Alkaline battery.
