1. General
The digital fan speed controller thermostat HTW-31-F17 is to control the fan coil unit for heating and cooling control. This digital fan coil thermostat has built-in NTC 10K temperature sensor to detect ambient temperature. Causes of low-pressure alarms in central refrigeration and air-conditioning systems:
1) Dirty filter of air conditioner indoor unit:
Air circulation will absorb dust in the environment on the surface of the air-conditioning filter. Some users will ignore this problem. Day after day, the air-conditioning filter is too dirty and the evaporator freezes, causing the air-conditioning low-pressure alarm to malfunction.
Solution: Replace the air conditioner indoor unit filter.
2) The filter drier is dirty or the copper pipe is blocked by oil:
The copper pipe connection needs to be welded. Some copper slag cannot be cleaned completely by blowing dirt. The stolen goods in the refrigeration system will collect in the filter drier. During the operation of the air conditioning refrigeration system, there will be a temperature difference between the two ends of the filter.
Solution: When the filter is particularly dirty, the refrigeration system needs to be blown or cleaned again. The general treatment method is to replace the dry filter of the same model and specification.
