SL-803 room thermostat are used to control room temperature in commercial, industrial and residential environment via controlling fan coil units, motorized valve, motorized air damper, heating pump and so on.
Models are available for heating/cooling/ventilatio control of 2-pipe or 4-pipe fan coil units
It uses NTC to detect the room temperature and compares it with the set-point so as to automatically keep the room temperature stable.

Fuction
● Cool/Heat/Sleeping mode Changeover Control
● Fan Operation
Fan can be selected as manual or automatic 3-speed operation.
The manual 3-speed, High, Mid, Low fan.
While in automatic mode, fan speed depends on the difference between room
Temperature and set-point.
● Timing on/off
● Low temperature(freezing) protection mode
Thermostat auto start at temperature below 5℃, prevent frostbite.
Freezing protection can be selected as disabled(default) or enabled. In freezing protection mode(no such mode in cool only application) when thermostat is in OFF mode while the acquired temperature is below 5℃, the thermostat will start heat mode until the temperature rises to 8℃ or the thermostat is turned on.
● Temperature calibrations.
● .Sleeping model
Adjust the setting Temp automatically accroding to the thermal environment conditions.
● Data Memory: If the power cut off accidentally, it could be continuing to work by order if the power returns. This fuction is popular at hotel, Power house etc.
● .Hotel card-key control interface: changing into comfortable mode with putting in the card-key, and energy-saving mode with pulling out the card-key. (optional)
● .Infrared remote control (optional)
