WRT-3710 Thermostat adopts the technology of intelligent fuzzy control and ultra-thin design. It can integrate with the interior decoration and very suitable for heating, cooling and HVAC system.
Temperature setting range： 5～35℃
Temperature display range: 0～40℃
Fan speed: High, Medium, Low, Automatic
Temperature sensing: NTC Thermistor (10K)
Relative humidity: 90％RH
Environment temperature: -20-60℃
Power voltage：AC24V 50/60Hz
Electrical parameters：AC24V 3A
A、Fan coil unit and motorized valve control;
B、18 hours automatic timer;
C、Fan coil unit wind speed conversion--. High, Medium, Low, Automatic;
D、Locking function --- When locked, the temperature can not be set, and only heat & cool transfer, power on & power off and Fan speed setting ;
E、Lock hidden function--- This function can only operate in the thermostat power off.
F、Shell pieces for the silver or white colors.
①Can adjust freely during 5℃～35℃，and display the indoor temperature. The indoor temperature can also displayed even thermostat in power-off condition;
②18 hours automatic timer power on/off;
③4 regular Fan speed adjustment mode
④Can connected to 2 wire or 3 wire motorized valve (2 way or 3 way) or air damper;
⑤Cooling, heating mode;
⑥NTC Thermostat fault alarm;
⑦Initial setup temperature(25℃) can be adjusted;
⑧In the power off, press “Heat/Cool” key and then “∧” key within 1S, you can lock. press “Heat/Cool” key and “ ∨ ” key within 1S, you can unlock.
⑨Optional function: 1) Power-down memory function, If power-on again after accidental power-down, it can save the last working state;
⑩Optional function: 2) If the power is cut off by accident, the thermostat would be reset after recharge and return to the last working condition;
⑪Optional function: 3) Only output for valve open, and no output for valve close. When press the power, the normal close contact closed to start other equipment.
“Power” －Click this key, the thermostat is on. When press again, it is off.
“∨”and“∧” －Temperature setting key. Press “∨” once，the setting temperature would reduce and press “∧” once，the setting temperature rise 1℃.
“M” －The key for cooling/heating/Air and timing. Press this key repeatedly, and it would transit from cooling/ heating/Air. Press this key 3s, then Timer, Press the “∨” “∧”to set the time. Press “∨” key set time to 0 if you want to cancel the set time.
Press this key repeatedly and set auto,high, medium, low, auto condition. The fan state changes when press this key.
When the power is off, press “M” key, and then press “∧”within 1S, it will setup to limit temperature of Heating.
When the power is off, press “M”key, and then press “∨”within 1S, it will setup to limit temperature of Cooling.
℃ and ℉ － When the power is off, press “M”key, and then press “Fan” within 1S, can be changed between ℃ and ℉.
1.If thermostat is matched with automotive ball valve, there need 7 wires: Live wire, neutral wire, valve open wire, valve off wire, and high, medium, low control for fan coil unit.
2.If it is matched with automotive ball valve, there need 6 wires: Live wire, neutral wire, valve open wire, and high, medium, low control for fan coil unit.
3.If only to control fan coil unit, there need 5 wires: Live wire, neutral wire, and high, medium, low control for fan coil unit.
4.We suggest to install the thermostat after the completion of the interior decoration.
Dimension and schematic
1. Install the thermostat on the indoor wall vertically. The distance to the ground is about 1.5m so as to make sure the thermostat can get sufficient air and fix the room temperature.
2. Make sure the thermostat be placed away from direct light, windows and doors and cooking equipment or other heat sources.
