Honeywell Tradeline Chronotherm IV User manual

Wallplate Installation
The thermostat can be mounted horizontally on the wall
or on a 2 in. x 4 in. wiring box. Position wallplate
horizontally on the wall or on a 2 in. x 4 in. wiring box.
1. Position and level the wallplate (for appearance
only). The thermostat will function properly even
when not level.
2. Use a pencil to mark the mounting holes. See
Fig. 2.
3. Remove the wallplate from the wall and drill two
3/16 inch holes in the wall (if drywall) as marked.
For firmer material such as plaster, drill two 7/32
inch holes. Gently tap anchors (provided) into the
drilled holes until flush with the wall.
4. Position the wallplate over the holes, pulling wires
through the wiring opening.
5. Loosely insert the mounting screws into the holes.
6. Tighten mounting screws.
WIRING
All wiring must comply with local electrical codes and
ordinances. Refer to Fig. 3 for typical hookup. A letter
code is located near each terminal for identification.
CAUTION
Disconnect power before wiring to prevent
electrical shock or equipment damage.
1. Loosen the terminal screws on the wallplate and
connect the system wires. See Fig. 4.

APPLICATION
The T8611G Chronotherm® IV Deluxe Programmable Heat Pump Thermostats provide electronic control of 24 Vac
single-zone heat pump systems. Refer to Table 1 for a general description of the thermostats. All T8611 thermostats
require a common wire to supply power.
Table 1. Description of T8611 Thermostats.
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.
Contact your local waste management authority
for instructions regarding recycling and the proper
disposal of the old thermostat.

Using Thermostat Keys
The thermostat keys are used to:
•set current day and time,
•program times and setpoints for heating and cooling,
•temporarily override program temperatures,
•display present setting,
•configure Installer Setup,
•check System-Test,
•display outdoor temperature (select models),
•set the system operation,
•set the fan operation.
See Fig. 6 for the location of the keys.
NOTE: Always press the keys with your fingertip or
similar blunt tool. Sharp instruments like a pen
or pencil point can damage the keyboard.
SETTINGS
System and Fan Settings
The system default setting is Heat and the fan default
setting is Auto. Use the System and Fan keys to change
the settings. See Fig. 7. The fan settings can be set for
each program period individually. The system selection is
for all the program periods.
System settings control the thermostat operation as
follows:
Em Heat: Emergency heat relay is on continuously.
Thermostat cycles highest stage of heat. Cooling
system is off. Compressor is de-energized.
Heat: The thermostat controls the heating.
Off: Both the heating and cooling are off.
Cool: The thermostat controls the cooling.
Auto: The thermostat automatically changes between
heating and cooling operation, depending on the
indoor temperature.
Fan settings control the system fan as follows:
On: Fan operates continuously.
Auto: Fan operates with equipment.
LED Indication
Two LED indicators are located in the upper right of the
thermostat. They indicate when a CHECK or FAIL signal
is sent to the thermostat from the system. See Fig. 3.
Temperature Settings
Refer to Table 2 for the default program. If the daytime
energy savings period is not used, press the period key
(Leave or Return) until the time is blank.The fan setting
feature is available on select thermostat models. See
Owners Guide, form number 69-0940, for complete
instructions on changing the program.
Fig. 4. Proper wiring technique.
Mounting Thermostat
1. Engage tabs at the top of the thermostat and
wallplate. See Fig. 5.
2. Press lower edge of case to close and latch.
NOTE: To remove the thermostat from the wall, first pull
out at the bottom of the thermostat; remove
top last.

settings will not need to be changed. Review the
factory settings in Table 2 and if no changes are
necessary, go to the Installer System-Test
section.
The Installer Setup is used to customize the thermostat
to specific systems. Some of the options include
temperature display, changeover and outdoor
