How do I get my honeywell system up and going?


for now, put switches on thermostat to hear and press the up arrow button to the desired temp. All your programed temps will take more explaining and it would be best you secure a owners instruction book from home depot. oif anything, buy thr same thermostat and either keep it or return it . I'd keep it regardless, read the pmphlet,program you heat and a/c before returning for refund. Don't destroy packaging and give them back everything. You will also need two AAbatteries. Good luck.

Uotside unit blowing cool air but hot on the inside


It sounds like you have a unit called a heat pump. When a heat pump unit is in cooling mode the outside unit blows hot air and the inside unit blows cold air. If the outside unit is blowing cold then the indoor unit is most likely blowing room temperature or warm air. It sounds like the thermostat could be controlling incorrectly or you could have a failed reversing valve which is the device that switches the unit from heating to cooling mode.

No heat in zone with Honeywell rth230B


It is not your thermostat, it is an airbound zone. The gurgly noise you heard was that water and air flowing through the radiator. The zone needs to be purged either at the boiler, or through vents on the radiator. Hope this helps
