Screen Indicators

OPERATING PRINCIPLES
HT270 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 symbol gives information about the operation status of the boiler. The product measures 0.1oC temperature accuracy. However, there is an operating sensitivity of 0.5oC 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 difference of the device is 0.5oC.

Calibration
The room thermostat can be calibrated if the measuring temperature wanted to be changed. The calibration range is -8oC to + 8oC.

ORDERING

When ordering, specify both the product type and the product code, for example the HT270 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.

MODEM

• Modem Led Light
• Sync Button:
  • Syncs modem and room thermostat.
• Manual Usage Button:
  • Deactivates receiver and allows you to use boiler manually.
• Modem Power Cable Input
• Boiler Connection Cable Input

MODEM LED LIGHT COLOR EXPLANATIONS

Green	Receiver synced with thermostat and Works properly.
Green Flashing	Pressed to receiver sync button and waiting for thermostat sync signal.
Red	Receiver has energy but no thermostat synced.
Red Flashing	Boiler shut down because of, no signal from thermostat more than 22 minutes.
Orange	On Manual Mode.

MODEM PLACEMENT
The important thing to note for receiver placement is that avoiding physical contact with boiler and protecting against materials such as liquid, dust etc. You can place your receiver in boiler’s cabinet without physical contact with boiler or mount receiver to Wall.

MODEM SETUP

• First, shut down the electrical current to which your boiler is connected (fuse, power outlet etc.)
• Connect one of the boiler connection cables to receiver as shown in the Connection Scheme.
• Connect other boiler connection cable end to boiler’s room thermostat input as shown in the boiler’s user manual.
• Input receiver power cable first to the receiver than to plug. If there is no plug near your boiler, you can connect cable to your boiler’s connection fuse.
• After finishing the connections, turn on electrical current first, then turn on your boiler.
• If you want to deactivate your receiver, press manual button for 2 seconds then you should see orange light on receiver. After being sure that your boiler is working, press same button and see orange light disappear.
• Setup Room Thermostat to sync receiver with room thermostat.
