THE ROUND® CREATIVE SERIES Y460A2003 THERMOSTAT

Disconnect wires from 
the old thermostat
 
or 
subbase. Wrap the 
wires around a pencil or 
other object, as shown, 
to prevent them from 
falling back into the wall 
opening. 
NOTE:  As you disconnect each wire, use masking 
tape to tape the end and label with the letter of 
the terminal designation to allow easier recon-
nection to the new subbase.
Keep the old thermostat for reference until your new 
thermostat is functioning correctly.
RECYCLING NOTICE
If this control is replacing a control that contains 
mercury in a sealed tube, do not place your old 
control in the trash. Dispose of it properly.
Contact your local waste management authority for 
instructions regarding recycling and the proper disposal 
of the old thermostat. If you have questions, call the 
Honeywell Customer Response Center at 1-800-468-
1502.
4 MOUNT THE SUBBASE
IMPORTANT:
Install your thermostat about 5 ft (1.5m) above 
the floor in an area with good air circulation at 
average temperature. Do not install it where it 
may be affected by:
— drafts, or dead spots behind doors and in 
corners.
— hot or cold air from ducts.
— radiant heat from sun or appliances.
— concealed pipes and chimneys.
— unheated (uncooled) areas such as an outside 
wall behind the thermostat.
Bring the thermostat cable through the subbase 
entrance hole.
Fasten the subbase to the wall or outlet box with the 
mounting screws as shown in the illustration.
Tighten the screws after using a spirit level or plumb 
line to accurately level the subbase. It must be level 
to maintain accurate calibration.
5 WIRE THE SUBBASE
Follow the instructions provided by the heating or 
heating/cooling equipment manufacturer. If not 
available, refer to the thermostat wiring diagram.
NOTE:  All wiring must comply with local electrical 
codes and ordinances.
Wire the Subbase
Refer to the illustration to strip the thermostat wire 
insulation from the wire where it connects to the 
terminal, as necessary.
Refer to the labels you placed on the wires when you 
removed the old thermostat. Match the letter of your 
old thermostat wire with the corresponding terminal 
letter on your new thermostat.
Connect the wires to the matching terminals on the 
subbase. If your old thermostat had an R terminal, 
and your new one has RC and RH terminals, 
connect the old wire R to terminal RH, and add a 
small piece of wire to use as a jumper to connect RC 
to RH. The drawing shows how to jumper RC to RH.
