The instruction below has been prepared to assist you enjoy using your Climaset
safely for many years. Please read this instruction thoroughly before starting to use
the device.
Each room fan coil or other type of air conditioning device should be protected
by its own mini circuit breaker (MCB).
Each room thermostat is designed to control a single room fan coil or other type
of air conditioning unit. We do not recommend control of multiple room fan coils
with a single thermostat.
May you ever encounter device malfunction, shut down the respective MCB and
contact the customer service. You may find proper recommended MCB’s rating
in Appendix A.
If you ever noticed that your air conditioning unit is not protected by a MCB, ask
your electrician to add one for you.
The MCB ratings should be selected according to required current for normal

operation of your air conditioner. Using higher ratings, you will not be protected
in case of emergency.
Your thermostat also protects itself as well as your air conditioner by a fuse. In
case of a burnt fuse, please check your system integrity. It can be a warning for
malfunction of your air conditioner or thermostat or short circuit of the wiring.
Always replace with the same kind of fuse. Fuses have several specifications
beyond their ratings. Check specification section for your fuse specification.
Contact your local customer service if you have already used your extra fuse.
Never bridge the fuse with wire or replace with higher rating fuses.
Use wire harness supplied with the device, before you screw the wires to the
thermostat terminals. It will avoid the possibility of short circuit. We
recommend using AWG 16 (1.5 mm) cables.
Never use detergent to clean the thermostat surface. It may leave undesirable
marks on the surface of thermostat, especially on the screen part. Always use a

soft moist tissue to clean the device.
Should the screen break, avoid direct contact of the leaked liquid crystal with
your skin, eyes or your mouth.
The device is not designed to work in very humid condensing places.
Strong electromagnetic fields, like the one with a radio transmitter, can interfere
with the screen content or cause device malfunction.
Never try to fix the device yourself. Replacement of the parts may affect the
device safety. Always contact your local Climaset service center for repairs.

2. Normal operation mode
It is the functional mode of the air conditioner. The thermostat restarts the air
conditioner whenever the room temperature falls below the set point in heating
mode or raise above the set point in cooling mode more than the specified swing
temperature (0.5 ˚C by factory default).
NOTE
Choose standby mode if you do not use a room for an extended period of time,
such as the time you are in a journey or when it is empty for most of the time and
only be used for special occasions.
In this mode, the thermostat shows the room temperature together with all of your
settings on the screen while the air conditioner apparatus is off.
1. Standby mode

The default swing temperature is set to 0.5 ˚C by the factory. If you like to
change it, refer to Appendix C.

5 Continuous fan operation
If the continuous fan operation is selected, the fan never switches off unless you
power off the device. Instead, when the room temperature reaches to the set point,
the fan continues blowing air without heating or cooling with the selected fan speed
in manual mode or switches to the lowest fan speed in the automatic fan speed
changeover mode. Refer to appendix C for more on continuos fan operation.
6 Automatic / Manual fan speed changeover modes
Automatic fan speed changeover mode:The fan speed is calculated and
applied automatically according to the difference between the room temperature
and the set point. By approaching to the set point, the fan speed reduces and by
getting away, it rises automatically. After the room temperature matches the set
point, it either switches the fan off in the normal operation mode, or continue with
the minimum fan speed in the continuous fan operation mode.
Manual fan speed changeover mode: By selecting this mode, the air
conditioner operates with the fixed selected fan speed. After the room temperature
reaches the set point, it either switches off heating or cooling and just blow the air if
the continuous fan operation is selected, or switches the fan off otherwise.

It represents if the thermostat activates air conditioner heating or cooling. If more
than one stage of heating or cooling is available, the stage number will be indicated
by a small figure beside heating or cooling indicator.
I Recycle delay
If the thermostat controls a compressor directly, a predetermined recycle delay is
necessary to prevent the successive restart of the compressor which may cause
jamming of the compressors electro motor due to high pressure. Normally a 3
minutes recycle delay guarantees that the pressure is equalized before restarting.
NOTE The actual number of available fan speeds is depend on your thermostat
model and your air conditioner capabilities.
