Control a heat pump with a wall thermostat?
I have recently installed an airsource heat pump in my vacation house in central Vermont. It works great, and mostly replaces the electric baseboard heating.
My concern is that the unit can only be controlled by a hand held remote, and only goes down to 60 degrees. We normally leave the house at 45 when we are away. It seems to me I am wasting a lot of energy now, perhaps using even more than the baseboards at 45.
I have an idea on how to fix this, but I’m not sure it’s a good idea. The unit is 240 volt. Could I just turn it on and off with a regular wall thermostat? In other words, when the room reaches temp, cut the power to the unit. When it cools off, restore power. Is this okay or would it be bad for the sysytem to be frequently turned off and on this way?
