3). Function
1.Can adjust freely during 0℃~40℃,and display the indoor temperature. The indoor temperature can also displayed even thermostat in power-off condition;
2.18 hours automatic timer power on/off;
3.4 regular Fan speed adjustment mode
4.Can connected to 2 wire or 3 wire motorized valve (2 way or 3 way) or air damper;
5.Cooling and heating mode;
6.Press “Heat/Cool” key and then “∧” key within 1S, you can set the ceiling temperature while heating, press “Heat/Cool” key and “ ∨ ” key within 1S, you can set the floor temperature while cooling.
7.Optional function: 1) Power-down memory function, If power-on again after accidental power-down, it can save the last working stat.
4). Instruction
1. “Power” -Click this key, the thermostat is on. When press again, it is off.
2. “∨”and“∧” -Temperature setting key. Press “∨” once,the setting temperature would reduce and press “∧” once,the setting temperature rise 1℃.
3. “M” -The key for cooling/heating and timing. Press this key repeatedly, and it would transit from cooling/ heating. 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.
Heating
→Cooling
4. “FAN” -Wind Speed Key.
Press this key repeatedly and set auto, high, medium, low, auto condition. The fan state changes when press this key.
Under the heating/cooling condition, the operation mode of fan is as follows:
Auto→high→medium→low
5. When the power is off, press “M” key, and then press “∧”within 1S, it will setup to limit temperature of Heating.
6. When the power is off, press “M” key, and then press “∨”within 1S, it will setup to limit temperature of Cooling.
7.℃ and ℉ - When the power is off, press “M” key, and then press “Fan” within 1S, can be changed between ℃ and ℉.

Functional Specification
In normal Internet connection, networking symbols will be displayed in the screen;
With the function of remote locking the thermostat keys, switching machine in local place is available;
5). Installation
1. If thermostat is matched with motorized 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 only to control fan coil unit, there need 5 wires: Live wire, neutral wire, and high, medium, low control for fan coil unit.
3. We suggest to install the thermostat after the completion of the interior decoration.
6). Wiring diagram and schematic
Wiring diagram and schematic 1---Model: WRT-3710N for 4-pipe FCU
Mode of connection:
1. Power line (250VAC): connection terminal live wire, valve on wire, valve off wire, high wire, medium wire, low wire and zero wire.
2. Network: outgoing line connection.
Outgoing via two groups of dual core shielded wires, a red wire and a white wire. Red: 485A, White: 485B
7). Dimension and schematic
8). Installation:
1. Install the thermostat on the indoor wall vertically. The distance to the ground be 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.
