Installation

The device is intended for indoor installation. Minimize the risk of moisture and liquid ingress at the installation site. The ambient temperature during operation and installation should be between –5...+45 °С.

‍The appliance is installed in a special box, which allows to conduct the easy installation and operation. Cabinet should be equipped with standard mounting rail 35 mm width (DIN rail). The appliance takes in width of 2 standard module on 18 mm. The height of the appliance should be in the range 0,5...1,7 m from the floor.

‍For protection against short circuit and excess capacity in circuit load necessarily need to set in front of the appliance, the automatic circuit-breaker (QF), see schemes 1, 3. To protect person from electric shock  leak is set safety shutdown device.

‍Terminals of the device designed for wire cross section up to 16 mm². Clean the end wires of 10±0,5 mm. It is advisable to use a soft wire, which is tightened in the terminals with a screwdriver with a tip width of no more than 6 mm with a torque of 2,4 N·m. A screwdriver with  a blade more than 6 mm wide can cause mechanical damage to the terminals. Doing so will void your warranty claim.

Сonnection schemes

‍Supply voltage (100 ~ 420 V, 50 Hz) served on terminals 1 and 2, phase (L) is connected to terminal location 1, the neutral conductor (N) to terminal 2.

‍The connecting voltage wires connected to terminal 3 and 4: phase (L) is connected to terminal location 3 and the neutral (N) to terminal 4. If a circuit without bypass of neutral through D2 is used, the neutral wire can also be connected to terminal 4.

‍Important❗️ Before the installation and operation of the device, please read by the end of this document. This will help to avoid possible danger, mistakes, and misunderstandings.

Exploitation

‍When connected and during operation, the thermostat displays the current temperature of the remote sensor. If it is lower than the set temperature, the load is energized. In this case, the indicator lights up red.

‍Use "+" or "–" buttons to change the heating temperature. First, the screen displays the operating mode, then the set temperature of this mode.

If you want to securely protect the settings from children or unauthorized access, press and hold the "+" and "–" simultaneously for 6 seconds until "Loc" appears on the screen, or in case of unlocking, "unLoc" will appear.

Menu button "≡"

Use the "≡" button to navigate through the menu.

Use the "+" and "–" buttons to change the parameters. After first pressing parameter will flash, after second pressing it will change. After 10 seconds after pressing — display returns to the mains voltage. To browse the abbreviation expansion of parameters, use the "і" button.
