Honeywell HH07AT216 Quick Manual

These Thermostats provide 24 to 30 Vac control in
single-stage heating-cooling systems. An spdt mercury
switch makes R to W on temperature fall for heating, and
R to Y on temperature rise for cooling. Integral switches
control COOL-OFF-HEAT system operation and ON-
AUTO fan operation. Heat anticipation is adjustable,
0.18A to 1.0A. See Fig. 1.
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 properly.
Contact your local waste management authority for
instructions regarding recycling and the proper disposal
of an old control. If you have questions, call Honeywell
Customer Relations at 1-800-468-1502.

tion at average temperature.
Do not mount the thermostat where it can be affected
by:
— drafts or dead spots behind doors or in corners.
— hot or cold air from ducts.
— radiant heat from the sun, fireplaces or appliances.
— unheated (uncooled) areas such as outside walls
behind the thermostats.
This thermostat is a precision instrument and was
carefully adjusted at the factory. Handle it carefully.

Disconnect power supply before beginning installa-
tion to prevent electrical shock or equipment damage.
All wiring must comply with local codes and ordi-
nances.
M5601
The thermostat can be mounted directly on a wall or
horizontal outlet box.
To wire and mount thermostat:
1. In replacement applications, check the existing
thermostat wires for cracked or frayed insulation. Re-
place any wires in poor condition. If the wire is plastered
into the wall, make a hole next to the wires and loosen
the wires so that they can be pushed back into the wall
later.
