PREPARATIONS

• For two wire systems (Heat Only or Cool Only).Ifyouhaveatwo-wireHeat Only  

system, attach one wire to RH and one to wire W. If you have a two-wire Cool Only  

system,attachonewiretoRCandonetowiretoY.Leavethefactoryinstalledjumper  

between RC and RH attached. Tighten any unused terminals securely.  

Assemble tools required: power drill, flat blade screwdriver, wire cutter/stripper, level.  

Failure to follow and read all instructions carefully before installing or operat-  

ing this control could cause personal injury and/or property damage.  

•

If your system has more than two wires: Use the cross reference chart to  

determine correct wire connections. If you have a four-wire heat/cool system leave  

thefactoryinstalledjumperbetweenRC andRH attached(seeFig2.).Ifyoursystem  

has five wires remove the factory installed jumper between RC and RH (see Fig 3.).  

• Electric heat or single stage heat pump systems: 1F56-306 energizes the fan  

on call for heat. Other thermostats are configured from the factory to operate a heat/  

cool, fossil fuel (gas, oil, etc.) forced air system. This is correct for any system that  

DOESNOTrequirethethermostattoenergizethefanonacallforheat.Ifyoursystem  

isanelectricheatorheat-pumpsystemthatREQUIRESthethermostattoturnonthe  

fan on a call for heat, remove the yellow factory-installed jumper wire from the Y  

terminal and connect it to the A terminal. This will allow the thermostat to energize  

thefanimmediatelyonacallforheat. Ifyouareunsureiftheheatingsystemrequires  

the thermostat to control the fan, contact a qualified heating and air conditioning  

service person. For single stage heat pump applications (no auxillary heat), install a  

short jumper wire (not included) across terminals W and Y. If the system has a  

reversing valve connection energized in Cooling, attach it to O. If the system has a  

reversing valve connection energized in Heating, attach it to B (see Fig. 4). This  

thermostat will not provide multi-stage heating or cooling.

D. Mount Thermostat Base: Gently push excess wire back into the wall  

opening and plug hole with a fire-resistant material, such as fiberglass  

insulation to prevent drafts from affecting thermostat operation. Mount  

the thermostat base to the subbase using the three captive screws on the  

thermostat base. (See Fig. 1) Tighten the screws securely. Remove  

paper tag from plastic contact cover. Proceed to Step #5.

▲ CAUTION  

To prevent electrical shock and/or equipment damage, disconnect electrical  

power to the system at the main fuse or circuit breaker until installation is  

complete.  

!

▲ ^CAUTION  

Take care when securing and routing wires so they do not short to adjacent  

terminals or rear of thermostat. Personal injury and/or property damage may  

occur.  

Before removing wires from old thermostat’s switching subbase, label each wire with the  

terminal designation it was removed from.  

1. Remove Old Thermostat: A standard heat/cool thermostat consists of three basic  

parts:

* These are four-wire, single-transformer systems. Factory installed jumper wire  

between the RH and RC terminals must remain in place.  

The heat anticipator pointer, if adjustable, will be set at one of a series of numbers  

representing the current rating of the primary control in your furnace. The number will be  

one of the following: .2, .4, .8, etc. or 0.2, 0.4, 0.8, etc.

EMERSON 1D56-310 White-Rodgers Low Voltage Horizontal Mounting Thermostat Instruction Manual Overview

Summary of Contents

• Page 1: If no heat anticipator/indication is showing, do not be concerned; move on to the next step. This product may or may not contain mercury. Do not open mercury cells. If a cell becomes damaged, do not touch any spilled mercury. Mercury must not be discarded in household trash. When the unit this product is replacing is to be discarded, place it in a suitable container for proper disposal. Thermostat installation and all components of the system shall conform to Class II circuits per the NEC code. Failure to follow and read all instructions carefully before installing or operating this control could cause personal injury and/or property damage. To prevent electrical shock and/or equipment damage, disconnect electrical power to the system at the main fuse or circuit breaker until installation is complete. Before removing wires from the old thermostat’s switching subbase, label each wire with the terminal designation it was removed from. Make a note of the anticipator setting on the old thermostat for future reference.
• Page 2: Factory-installed jumper Set heat anticipator to match the setting of your old thermostat or the current rating stamped on your main heating control. The heat anticipator is adjustable from 0.15 to 1.2 amps. Adjust the anticipator by rotating the contact arm. This thermostat is easy to operate. Use the system switch to select either heating or cooling, or to turn the heating/cooling system off. When the fan switch is in the AUTO position, the fan will cycle with the heating or cooling system. Electrical data includes switch rating of 24 VAC (30 VAC max.) and heating from 0.15 to 1.2 amps. Troubleshooting common problems includes checking for blown fuses or tripped circuit breakers. Verify thermostat and system wires are securely attached if experiencing no heat or no cool.
