Mechanical Thermostat Switch Control
Mechanical thermostat switch control is used in commercial, industrial and civil buildings to control the end coil fans and water valves of central air-conditioning for heating and cooling. Keep the ambient temperature of the controlled place constant within the set temperature range. The temperature setting dial pointer should be set to the desired constant temperature position. The toggle switch functions are: power switch (ON-OFF OFF); operation mode switch (HEAT-cooling COOL), FAN wind speed switch (low speed L-medium speed M-high speed H). Controllable equipment: three-speed fan-coil wind speed, three-wire electric valve, two-wire electric valve, solenoid valve, on-off air valve or three-wire air valve can also be connected.
Features
Used to control a variety of equipment such as fan coils, electric valves, dampers, etc.
The switch adopts the toggle type, which is comfortable to the hand and has a long life.
Set the temperature through the knob (the temperature range can be limited)
The thermostat can be directly mounted on the wall or standard junction box
Cold/heat conversion control
Indoor temperature setting
specifications
1. Rated voltage: 230VAC±10% 50/60Hz
2. Load current: <3A resistive load
3. Temperature deviation: ≤1℃ at 25℃
4. Ambient temperature: -25℃~55℃ relative humidity <85% (23℃)
5. Dimensions: 130X85X40 (length X width X thickness)
Note
1. When the system is turned off, the switch is in the OFF position, and the No. 2 terminal still has voltage, which can ensure that the three-wire electric valve is closed. Therefore, all power supplies should be cut off when the system is maintained, otherwise it is easy to cause electric shock.
2. Built-in temperature compensation element, if there is no neutral wire (N) connected to terminal 3 or 4, it will affect the accuracy of temperature control.
