Hi
Remove the C wire
Connect a jumper between Rc and R and Tape off the C as C is comman and is only used for the power to display
-
No, UV lights are just used to clean the air and its not unnecessary to install if not required.
-
Hi
Please check if you have any wire on Rc or not
If you don't have a wire on Rc then put a jumper bteween R and RC because heat is controlled by R and cool and fan is controlled by Rc, if you have...

Hi
First check on the furnace which colour wire is connected to which label (alphabet)
And then match the same on the stat

hi
this is a heatpump wiring
wiring is as follows:
R-R^Rc
T-tape off
O-O/B
G-G
Y-Y
X2-E
B-tape off

Hi
If u not a licenced contractor I will suggest to work with a professional/contractor but if u are a contractor then u can call honeywell contractors helpline-1800-468-1502 option 2 for...

Please don't follow the colours as the Honeywell don't follow any standard colour code
-
The easiest way is to trace the wires from air handler and get the lables, then match the labels on the stat and wire it up, u also have to set the functions on the stat
If it's a Heatpump with...

Hi
None of the digital stat will work
Need to get Honeywell CT30A.
Because u have 2 wire heat and AC.
-
hi
need to check the W1 if its connected on the system or not
if its connected on the system this stat will not work because then your system will be 3heat/1cool heatpup
this stat can only...
-
Hi
That stat need 20Vac-30Vac to work
Need to check the voltage between the wires
If the voltage is less than 20Vac or if there is no voltage need to work with a professional
The wiring is...

Try this

Hi
This usually happens due the feedback coming from system to the stat.
To check this pull the stat off the wall,if wait changes to HEAT ON,then the stat is fine
Need to work with a contractor...

Hi
When you turn your system switch to cool fan to auto
Do you see a snowflake icon
If yes,do you feel the sir from the vents
If you feel air but its not cool
Check if your compressor is...

Hi
There can be two possibilities
1) u have heat only application
2) u have heat and cool both ,in this case u should have a heat cool changeover switch on the system it self.
In 2 wire system...

Hi
As you mentioned , used terminals are R,W,Y,G
In this R is power,W is heating ,G is fan and Y is compressor
In RTH2300B when you run Ur cooling,do you see word cool on on display,if cool on...
-
R and G will let your fan run
Are you sure it's a heat pump
Where is the reversing valve.
Recheck the wiring
Its can be 2 stage EFA + AC (heta strips in same unit)
-
hi
first of all don't go by colour codes
I think u have connected the blue wire to O/B on honeywell stat and that might be the reason why its running contaniously
u can use the stat with R on...
-
Hi
Nobody can advied about a line voltage stat
Because
U have to get the voltage,amps,watts between the wires and above all there are 2 sets of stats.one which is compatible with a inductive load...
-
Which type of heating system is it-if it's a Gas Furnace then in a gas furnace the fan is controlled by the system it self.
U can try 1 thing
If system is in off mode and fan in in auto
If fan...
-
In a 2 wire system u also need to check the voltage
Mostly stats works between 20-30Vac or 750 milli volts but some stats might not work on 750 millivolts
In 2 wire system we require battery...

hi
T8411R is a multi stage heatpump stat,I think the wires were connected to C,G,Y^W,O,R,W2 but if u have not labelled the wires then don't assume ,trace the wires from the air handler
RTH6300B is...

Rth230b is a digital stat is +/- 1 degree accurate
But u also have u check what's is the status of flame icon.
If fan stops and flame icon disappears that's means its satisfing the set point
But...
-
Flashing snowflake on the stat is due to compressor protection time if which between 3-5 min,it's a feature to prevent compressor from being getting damaged
-
The click on the thermostats are only when there is a call for heat/cool and when the set temp is satisfied

hi
every child is the most precious thing in the life of there parents,I can understand what u are going through but I think they are concerned for u that's why they want you to be normal and happy...

Hi
Honeywell don't follow color code
Have u labelled the wires before disconnecting
If yes,then check for wires,pins and breaker
Should be tight and secure,furnace door should be closed
Also...

Hi
This only happens when there is alimit issue with your ayatwm that means the efficiency of your heating system has gone down
Get the system checked from a contractor
-
No RTH221B1021 does not have a backlight
-
hi
first of all this is a professional thermostat and should be installed only by a contractor,however
O-O/B
Y-Y
G-G
E-E
C-C
R-R^Rc
as per wiring it seems to be Heatpump all electric
-
I will advice to get Honeywell RTH7500D or RTH6350D.
It will be compatible
