OP: All of the honeywell thermostats that are compatible with Heat Pumps and an outdoor sensor will have the lockout in the menu. It looks like you're new here. in the hydronic loop, Overcharged refrigerant circuit, Expansion valve / … Is it 4 heat stages? On heat pumps the indoor coil becomes the condenser in the wintertime and if you are not getting enough airflow across the indoor coil it with cause the high-pressure code problem. It can also cause a malfunction in the system that will lead to reduced capacity for cooling and heat (for a heat pump) or the system not functioning at all. If this switch needs resetting on a heat pump, it means the head pressure or the high-pressure side of the heat pump is exceeding maximum pressure. A restriction in your refrigeration cycle like a bad TXV (thermostatic expansion valve) or a stopped up orifice can also cause high-pressure problems. Measure operating pressure (inches w.c.). The bonus room is included in the 3,997 square feet and is about 600 square feet on its own. 1.03Have you noticed if the defrost cycle is normal?Not sure how to check this.Is it one zone or multi zone with the Infinity dampers?No blocked vents?

This takes hot water from boiler and loops it through air handler and uses that warm air to heat rooms by duct work. + Check injection pressure during start-up (Value for High Heat) + Remove the air from the Gas pipe-work + Adjust the injection pressure to high heat value. As a rough guide to the pressure ranges that occur with the various refrigerants, consider the pressures at a condensing temperature of 60°C. High Pressure When this light is on, it indicates high refrigerant pressure. Of course. Learn more. High Head pressure for a refrigeration system, including a heat pump or air conditioner can cost you more money and possibly lead to premature failure of the compressor.
