My new system:
Condenser: Carrier 24ACB736A003 (two stage)
Coil: Carrier CSPHP4212ATA
Furnace: Carrier 58PHA090-16 Furnace (ECM motor)
Media Filter: Honeywell F100
Thermostat: Honeywell VisionPro 8000 with Humidity Sensing
I live in southeast Texas. I went for this system thinking that the enhanced de-humidification of a two-speed system would be worth it. It appears to be a very popular system in my area. I had two MAJOR Carrier dealers quote me the same system, and they both referred to it as their standard "gold" system, for what thats worth. I've only owned the system for two weeks now and I'm already having remorse.
I'm presently running the thermostat in "permanent hold" mode until we decide on how we'd like to program.
My first issue: the condenser unit never seems to go into low speed mode - its either on or off. For example, Temp setting: 75F, Humidity setting: 50%. When the thermostat reads actual temperature of 75F, if the humidity is still high, say 54%, the blower goes into low speed mode and the condenser shuts off. What combination of settings can I try to verify that the low-speed stage on the condenser unit is/is not working?
My second issue: in low-humidity conditions (yes! it happens here, albeit rarely), the system wants to increase humidity. For example, Temp setting: 75F, Humidity setting: 50%. When the thermostat reads actual temperature of 75F, if the humidity is lower than the humidity set point, say 43%, the blower goes into low speed mode and the condenser shuts off. After a few minutes the system is putting out tepid air, and will continue to do so until the room temperature rises above set point. I would really rather the system completely simply shut off instead of trying to raise the humidity. Is that even possible with my equipment?
Maybe its just the wrong thermostat for my preferences? Any help or advice would be welcome!!
