Smart Thermostat

Smart thermostat has incorporated all requirements and uses of air conditioning in the country. All different thermostat models have been included in one product.

In other words, all types of fan coil, split duct, and floor heating system are controlled only with one thermostat. You only need to choose your desired model prior to installing the device.

The device can be connected to all systems, working with differing voltages such as urban electricity 220 Vac, 24 Vac/dc, etc. In other words, the output voltage of thermostat will be equal to your desired voltage.

Smart thermostat with advanced setting will protect your cooling/heating system, allowing you to adjust all parameters of the device in accordance with the cooling/heating system and your taste. In addition, in order to increase the users' ease and decrease energy consumption, there are varied utilization scenarios in the device. To choose the air conditioning model, press and hold 8 for 20 sec., then by means of up/down keys, select the considered model and press 8 again.

Scenarios

This thermostat has 5 scenarios of Comfort, Economy, Sleep, Turbo, and Fan/Heat Schedule, which guarantees your comfort and peace.

Comfort: Normal device control
Sleep: Increasing the adjustable temperature for one degree after one hour, increasing the adjustable temperature for two degrees after two hours, and returning the temperature to the initial state after 8 hours
Economy: Setting the adjustable temperature on the selected number in advanced setting in order to decrease the energy consumption during your absence from home
Turbo: Changing the adjustable temperature to turbo scenario temperature and thermostat's performance
Fan/Heat Schedule: Turning the fan on/off in a determined time alternately

To choose the air conditioning model, press and hold  for 20 sec., then by means of up/down keys, select the considered model and press  again.
