If you're working on one in heating mode, when it's about at the freezing point outside, how would you decide if the charge is right or not and do better than a guess?. Use the Up and Down arrows to change the configuration. Since heat pumps provide both cooling and heating, they are rated according to how efficiently they cool (SEER) and how efficiently they heat (HSPF). So what about the heat pump thermostat? If you have a heat pump you don't have a furnace since the heat pump provides cooling and heating. Here are the steps and tools needed to install a heat pump. All manufacturers, except a few (Rheem and Ruud among a few others), energize the reversing valve for the cooling cycle. 7 Set Heat Pump Reversing Valve O Leave the jumper in this factory-set position if you have connected O wire to the O/B terminal. Taco Zone Sentry Zone Valves provide on-off, normally open or normally closed control in both open and closed hydronic systems. When the outdoor temperature drops below this setting, the thermostat will stop using the heat pump for heating and only use the auxiliary heat. by air entering the pump suction inlet. If your diesel high pressure fuel pump is faulty this will cause low pressure (see low fuel pressure). You are starting-up a split system heat pump for the first time.
