INSTALLATION
Installation
COMPATIBILITY
The T8611 Thermostats will replace most heat pump system thermostats. As long as ac power is continuously available to the thermostat, the thermostat will be compatible with almost any low-volt control system.
WHEN INSTALLING THIS PRODUCT…
1.Read these instructions carefully. Failure to follow them could damage the product or cause a hazardous condition.
2.Check the ratings given on the product to make sure the product is suitable for your application.
3.Installer must be a trained, experienced service technician.
4.Allow thermostat to warm to room temperature before operating.
5.After installation is complete, check out product operation as provided in these instructions.
! CAUTION
Disconnect power supply to prevent electrical shock or equipment damage.
LOCATION
Thermostat with Integral Sensor
Install thermostat and subbase about 5 ft. [1.5 m] above the floor in an area with good air circulation at room temperature.
Do not install the thermostat where it may be affected by--
--drafts or dead spots behind doors, in corners or under cabinets.
--hot or cold air from ducts.
--radiant heat from sun or appliances.
--concealed pipes and chimneys.
--unheated (uncooled) areas behind the thermostat, such as an outside wall.
Thermostat with Remote-Mounted Sensor
Install thermostat in an area that is accessible for setting and adjusting the temperature and settings.
Install remote temperature sensor in an area with good air circulation at average temperature.
Do not install the sensor where it may be affected by--
--drafts or dead spots behind doors, in corners, or under cabinets.
--hot or cold air from ducts.
--radiant heat from sun or appliances.
--concealed pipes and chimneys.
--unheated (uncooled) areas behind the sensor, such as an outside wall.
IF REPLACING AN EXISTING THERMOSTAT
Turn thermostat power off at furnace or heat pump.
This thermostat requires a single transformer. A twotransformer system may require turning off two switches or disconnects, and rewiring to run the thermostat from a single transformer. Make sure the transformer has adequate power (VA) for the heating/cooling control system. Add current ratings of the system components (such as auxiliary heat relay, changeover relay, fan relay). Multiply this total by 24V to determine transformer VA required.
Remove any existing wallplate or subbase from wall. Label or write down each wire color with the letter or number on the wiring terminal as the wire is removed to avoid miswiring later.
IF NEW INSTALLATION
Run cable to a hole at the selected wall location for thermostat and remote sensor, and pull about 3 in. [76 mm] of wire through the opening. Color-coded, 18-gauge thermostat cable with at least one conductor for each wiring terminal is recommended. Good service practice recommends selecting cable with one or two more conductors than the immediate application requires.
If using thermostat model with remote temperature sensing, run 3-wire, 18-gauge thermostat cable from the thermostat location to the sensor location (200 ft. [61 m] maximum). Route cable away from sources of electrical noise.
MOUNTING SUBBASE
IMPORTANT: Set the subbase system switch in the OFF position before mounting.
The subbase does not require leveling for operation, but
for appearance only.
Remove thermostat from subbase (Fig. 4).
Fig. 4—Removing thermostat from subbase.
The subbase mounts directly onto the wall with the screws and anchors included. Instead, the subbase can be mounted on a vertical or horizontal outlet box. If you must mount the subbase on a vertical outlet box, order 193121A Adapter Assembly. The assembly includes an adapter ring, two screws and a cover plate to cover marks on the wall. Install the ring and cover plate on the vertical outlet box as instructed.
Use the subbase as a template, and with a pencil, mark the two mounting screw positions (Fig. 5).
If drywall construction, plastic anchors must be used; use 3/16 in. bit to drill holes for anchors. Gently tap anchors into holes until they are flush with the wall surface.
Thread wires through the center opening of the subbase.
Mount the subbase using two screws provided. Gently tighten screws, level top surface of subbase, and securely tighten screws.
Fig. 5—Mounting subbase on wall.
MOUNTING REMOTE TEMPERATURE SENSOR (IF APPLICABLE)
The remote sensor mounts directly on the wall with screws and anchors included. Remove cover from remote sensor (Fig. 6). Use the remote sensor base as a template, and with a pencil, mark holes for mounting screws.

ADJUSTING CYCLE RATE
To customize the thermostat last heating stage cycling performance to various types of auxiliary heating equipment, a cycle rate adjustment screw is provided on the back of the thermostat to provide optimum savings and occupant comfort.
NOTE: MOST APPLICATIONS WILL NOT REQUIRE A CHANGE IN CYCLE RATE.
The room air temperature normally will vary slightly from the comfort temperature setting with the cycling of the heat pump or auxiliary heater.
Fig. 11—Cycle rate adjustment.
Fig. 12—Battery placement.
The Stage 1 cycle rate of this thermostat is factory-set for heat pumps and cannot be adjusted. The auxiliary heat cycle rate can be adjusted by turning the cycle rate adjustment screw on the back of the thermostat. See Fig. 11. Increasing the cycle rate will reduce room temperature swings when auxiliary heat is being used.
INSTALLING BATTERIES
Three AAA alkaline batteries are included to provide backup to prevent program loss in case of power outage. Install batteries in back of thermostat as shown in Fig. 12.
Without battery backup, the program will remain about 20 seconds in event of power loss.
Honeywell Chronotherm Iii Programmable Thermostat Manual
IMPORTANT: When batteries are first installed, the display will flash 1:00 PM and 32°. After a brief delay, the display will flash 1:00 PM and room temperature.
When the batteries are low, the display will flash REPL BAT. Homeowner will have 20-30 seconds to install new batteries after removing old batteries from back of thermostat. After20-30 seconds, it will be necessary to reprogram. REPL BAT indication will disappear within5-10 minutes when thermostat is remounted on the powered subbase.
IMPORTANT: For proper thermostat operation, always replace dead batteries with new alkaline batteries.
If batteries are completely dead, the display will go blank when the thermostat is removed from subbase. After replacing the batteries, reprogramming will be necessary.
POWER OUTAGES
Backup batteries will hold the programming and keep the display on during most power outages. Once the power is restored, the system will resume normal operation.
If the display goes off when power is lost, either the backup batteries need to be replaced or are not installed. When power is restored, the display will flash 1:00 PM to remind you to reprogram.

COOLING
! CAUTION
Do not operate cooling if outdoor temperature is below 50° F [10° C]. Refer to manufacturer’s recommendations.
NOTE: When cooling setting is changed, thermostat will wait up to five minutes before turning on the cooling equipment. This delay protects the compressor.
Move the system switch to COOL and the fan switch to AUTO. Press COOLER key until the setting is about 10° F [6° C] below room temperature. The cooling equipment and fan should start. Press WARMER key until the setting is about 10° F [6° C] above room temperature. The cooling equipment and fan should stop.
NOTE: On an AUTO changeover thermostat, the heating temperature must be set at least 3° F [2° C] below the cooling temperature, or display will flash.
FAN
Move the system switch to OFF, and the fan switch to ON. The fan should run continuously. When the fan switch is in the AUTO position, fan cycles with the heating or cooling system.
INSTALLER SELF-TEST (OPTIONAL)
IMPORTANT:
•Thermostat must have ac power to perform self-test.
