1. SELECT THE MODE (cont.)
• HEAT OR COOL (AUTO-CHANGEOVER) – HEAT or COOL appears on the display. Either
the heating or cooling equipment will operate to maintain the room temperature at or
above the HEAT setting and at or below the COOL setting. HEAT or COOL will flash when
the respective equipment is operating.
• EMERGENCY HEAT (EM. HEAT
for heat pump equipment only) –
EM. HEAT appears on the display
and only the back-up heat source
will be operated to maintain the
room temperature above the
HEAT setting. This is generally
more expensive than using the
heat pump (HEAT MODE), so
use accordingly. Typical usage
is when the heat pump has
malfunctioned.
• HEAT – HEAT appears on the
display and only the heating
equipment will be operated to
maintain the temperature at the
HEAT setting. HEAT will flash
on the main display when the
heating equipment is operating.

OPERATING THE THERMOSTAT
Notes on temperature adjustments:
• The COOL setting must always be a minimum of 2° (F or C) higher than the HEAT setting.
The thermostat will automatically maintain the 2° difference. For example, if the Cooling
set point is 75°F and one changes the Heating set point to 74°F, the thermostat will
automatically change the Cooling set point to 76°F.
• The lockout icon will appear on the display when attempting to make a change, if the
thermostat has been configured to be locked out or the desired change violates the ther-
mostat limits (i.e. lowest allowable HEAT setting is 40°F, highest allowable COOL setting is
90°F, etc.). Lockout configuration can be altered in set-up menu (
see page 10
).
1. SELECT THE MODE
The thermostat can be set to OFF, COOL, HEAT or COOL (AUTO-CHANGEOVER), EM. HEAT (for
heat pumps only), and HEAT modes. To set, press the MODE button until the desired mode
appears on the display (see
Figure 3
).
• OFF – Select the OFF mode to prevent the heating and cooling equipment from operating.
• COOL – COOL appears on the display and only the cooling equipment will be operated
to maintain the temperature at the COOL setting. COOL will flash on the main display
when the cooling equipment is operating.
