Factory direct three-speed switch

Analog fan coil thermostat (PI controller), 0-10V analogue fan coil thermostat, air conditioning coil temperature control three-speed switch is mainly used in central air conditioning heating and cooling systems. Generating a control signal by comparing the detected ambient temperature and set temperature for the central air-conditioning fan coil cold hot electric valve actuators or other amenity / temperature control, can control the fan coil while the fan is working and speed. Output 0-10V & 4-20mA or three floating output, power supply to 220VAC & 24VAC optional. MSRE07F when the power is turned on or off, turn off the thermostat can be reset output delay interrupt signals, so that the electric valves or other actuators reset.
