In the process of remodelling my condo. I've now come to the HVAC. I have a McQuay Hiline Model HSB 06AR Fan Coil unit running the heat and air conditioning. I suspect it mid 70's vintage, but still works very well. Like most McQuay, now Daikin units, the Thermostat controls the temperature, and the Fan is manual with Off, H M, L. I am planning to install a couple of relay switches between the Thermostat and the Fan, that will effectively turn the Fan off and on, with the thermostat and do away with the manual controls, because they run all the time. We're using relay switches to avoid having to run wires through the walls. My question is this: These units are built based on the fact that the fan runs continuously. Do I run the risk of screwing up the fan motor by converting to go off and on based on the temperature. Where I may have turned the fan off and on once or twice during the day, it will now go off and on all day and all night based on the temperature. Can anyone tell me whether or not this is a viable solution.
