When to use lower fan speed in heating mode?

It might make sense to have your fan speed at maximum all the time. However, in heating mode this isn’t always the case. During the winter months it is best to allow your heat pump to run at a lower fan setting and spread heat out more evenly over a longer period of time.

When does a fan run continuously on a thermostat?

In the “On” position, the fan will run continuously. Some new thermostats have an additional fan setting of “Circ”, which is short for “Circulate”. In this mode the fan will cycle on and off with the cooling, but it will also kick-on automatically if there is an extended period without a demand for cooling – to provide additional air circulation.

How does an indoor heat pump shut off?

The thermostat reaches the desired temperature, the indoor unit shuts off, the air stops blowing, but the outdoor unit keeps on running. In the heating mode (if it’s a heat pump) it could eventually shut off on a high pressure safety device. But in the cooling mode, it could run forever unless you turn the breaker off.
