White Rodgers 1F95-1280 Emerson Blue 12" Commercial Touchscreen Programmable Thermostat User Manual

Before removing wires from old thermostat, mark wires for 
terminal identification so the proper connections will be made 
to the new thermostat . 

1 .  Pull the thermostat body off the thermostat base . Forcing 

or prying on the thermostat will cause damage to the unit .

2 .  Place base over hole in wall and mark mounting hole 

locations on wall using base as a template .

3 .  Move base out of the way . Drill mounting holes . If you 

are using existing mounting holes and the holes drilled 
are too large and do not allow you to tighten base snugly, 
use plastic screw anchors to secure the base .

4 .  Fasten base snugly to wall using mounting holes shown 

in Figure 1 and two mounting screws . Leveling is for 
appearance only and will not affect thermostat operation .

5 .  Connect wires to terminal block on base using appropriate  

wiring schematic .

6 .  Push excess wire into wall and plug hole with a fire resis-

tant material (such as fiberglass insulation) to prevent 
drafts from affecting thermostat operation .

7 .  Carefully line the thermostat up with the base and snap 

into place .

2 "AA" alkaline batteries are included in the thermostat at the 
factory with a battery tag to prevent power drainage . Remove 
the battery tag to engage the batteries .
To replace batteries, set system to 

OFF, remove thermostat 

from wall and install the batteries in the rear along the top of 
the thermostat (see Figure 1) . For best results, use a premi-
um brand "AA" alkaline battery such as Duracell

®

 or Ener-

gizer

®

 . If the home is going to be unoccupied for an extended 

period (over 3 months) and 

 is displayed, the batteries 

should be replaced before leaving .

The Power Stealing Switches (Fig . 1) should be left in the 
"On" position for most systems . The information in the 
following table details the thermostat power method and 
switch options .

Battery Powered, no 24 
Volt system power available .

Switches 

"On", thermostat 

runs on batteries .

Hardwired with Battery  
Back-up, for 24 Volt systems 
with common connection from 
transformer to "C" terminal 
on thermostat .

Switches 

"On", thermostat 

runs on power directly from 
transformer with battery back-
up .

*Battery Powered with 
Power Stealing Assist, 
for 24 Volt systems with no 
common connection from 
transformer to "C"

 terminal on 

thermostat .

Switches 

"On", thermostat 

runs on batteries and 
supplemental power drawn 
through the heat or cool circuit .

*Power Stealing Assist is very reliable to increase battery life, 
but on a small number of heating or cooling systems with high 
impedance electronic modules you may observe one of the 
following conditions:
1 .  The furnace draft inducer motor may run with no call for  

heat .

2 .  The furnace fan may turn on with no call for heat or may  

not turn off .

3 .  The furnace may not turn off when the call for heat ends .
4 .  The air conditioner may not turn off when the call for cool 

ends .

If the Power Stealing Assist method is not compatible with 
your system, place the Power Stealing Switches to 

"Off" . This 

cancels Power Stealing Assist, operates the thermostat on 
batteries and corrects the condition .
