I have a two stage Bosch water to water geothermal unit. When I look at the thermostat it is maintaining the temperature I have set, but I am experiencing what seems to be a lot of cold air during stage 1 operation. It can get to the point where I feel like I have to put on warmer clothes. If I increase the temp setting it will eventually get too warm. Does this sound normal?
More information would be helpful. You say you have a water to water unit but your delivered air is cold?
