OPERATING PRINCIPLES
HT250 SET room thermostat specifications:
LCD with backlight
Two-position control (ON / OFF)
Temperature sensor (NTC)
The thermostat measures the room temperature with its temperature sensor. The desired temperature value is set
by turning the button to the right or left. When the room temperature rises above the set temperature value, the
room thermostat sends a shutdown command to the modem. Modem Turns off the relay by receiving the
command.
Digital display; The set temperature, battery life, room temperature and heating symbol are displayed. The heating
o
symbol gives information about the operation status of the boiler. The product measures 0.1 C temperature
o
accuracy. However, there is an operating sensitivity of 0.5 C to prevent the heating unit from starting and stopping
too frequently.
The device manages the heating systems by the on-off operation algorithm. This working algorithm is shown in
the following graph.
FUNCTIONS
Temperature Control
The room thermostat controls the room temperature according to the set value. The on / off temperature
o
difference of the device is 0.5 C.
Calibration
The room thermostat can be calibrated if the measuring temperature wanted to be changed. The calibration range
o o
is -8 C to + 8 C.
ORDERING
When ordering, specify both the product type and the product code, for example the HT250 SET wireless room
thermostat.

ROOM THERMOSTAT INSTALLATION
Remove the room thermostat by pulling it out of the wall bracket. If you want to use your room thermostat in a fixed
place, mount the dismantled wall apparatus in a room you frequently use in your living space. If you want to use
your room thermostat with the table bracket, place the room thermostat on the table bracket by removing the wall
bracket. For example; Like your home lounge or living room. Avoid installing the room thermostat where there is a
lot of air circulation, such as door entry or window edge. Also, do not place near heating units (heating panels,
fireplaces etc.) and direct sunlight areas. We recommend that the room thermostat is placed at a height of 50 cm
to 150 cm from the floor. You can try a few places to find where you can place the room thermostat.
If the room thermostat is to be used with the wall bracket, the wall bracket must be mounted on a flat wall.
Local electrical regulations must be observed during installation.
Installation of room thermostat must be done by authorized personnel.
The parts included in the room thermostat are made of ABS, PC materials.
In systems with room thermostats, if there are thermostatic radiator valves, keep them in the open position.
BATTERY CHANGE
Remove the battery cover located on the back of your room thermostat. Insert a 3V DC (2xAAA) alkaline battery
into the battery compartment. When installing batteries, make sure they are incorrect position. Place the room
thermostat in the wall bracket or table bracket by closing the battery cover. Replace both batteries at the same
time.
WARNING!
Please dispose of your discharged batteries in waste bin which is separated for battery wastes.
MAINTENANCE
The device is maintenance-free.
