NOTES:

• The keypad will not lock if the thermostat is operating in

configuration mode or test mode.

• When the user exits from configuration mode, the ther-

mostat keypad will lock immediately if the keypad lock-

out level is set to anything other than off.

Unlocking Keypad with Access Code  — When the keypad is

locked and a lockout code is required, pressing any button on the

keypad will display the lockout code as “

” in the time display.

Press an UP or DOWN arrow key to change the dashes to the ac-

cess code. When the correct 4-digit lockout code is displayed,

press the DONE button.

In the event that the installer or user cannot remember the un-

lock code for the thermostat, the code can be displayed if the

user presses and holds the soft key below the days of the week

and the soft key below the cooling set point simultaneously for

30 seconds. After the 30-second period, the unlock code will be

displayed for five seconds.  This information does not appear in

any user documentation.

The default is OF (off).

OPTION 22 — HIGH COOL LATCH TEMPERATURE —

An outdoor sensor is required for high cool latch feature and

Option 7 (Equipment DDC Controller) has to be set to OF (off).

This selection is not available if the equipment DDC  has been

set to On. Configuration settings are OF (off), 80, 85, 90, 95,

100, 105, 110 F (26.7, 29.4, 32.2, 35, 37.8, 40.5, 43.3 C) and On. 

When set to OF (off), cooling always starts in low stage (Y1)

and stages up to high stage (Y1 and Y/Y2) when demand is suf-

ficient and staging timer constraints have been satisfied.

When set to 80 through 110 F (26.7 through 43.3 C), this is

the outdoor temperature above which both first and second stag-

es of the compressor are energized to satisfy all cooling de-

mands. When a cycle starts under a high cool latch, it will finish

the cooling cycle on high stage. If the cooling equipment is ener-

gized to satisfy a dehumidification demand only (no cooling de-

mand), the latch will not be applied.

When set to On, the Y1 and Y/Y2 outputs are simultaneously

energized to satisfy all cooling demands.

The default is OF (off).

OPTION 23 — HIGH HEAT LATCH TEMPERATURE —

This selection is only available when Option 1 is set to HP and

Option 7 (equipment DDC controller) is set to OF (off).

Configuration settings are OF (off), 20, 25, 30,  35,  40,  45,

50 F (–6.7, –3.9, –1.1, 1.7, 4.4, 7.2, 10 C) and On. 

When set to OF (off), heating always starts in low stage (Y1)

and stages up to high stage (Y1 and Y/Y2) when demand is suf-

ficient and staging timer constraints have been satisfied.

When set to 20 through 50 F (-6.7 through 10 C), this is the

outdoor temperature below which both first and second stages of

the compressor are energized to satisfy all heating demands.

When a cycle starts under a high heat latch, it will finish the heat-

ing cycle on high stage.

When set to On, the Y1 and Y/Y2 outputs are simultaneously

energized to satisfy all heating demands.

The default is OF (off).

OPTION 24 — PROGRAMMABLE/NON-PROGRAMMA-

BLE

 — This selection allows the installer to configure the ther-

mostat as either programmable (P) or non-programmable (nP).

NOTE: If non-programmable is chosen, then the fan will run

only when there is a call for heating or cooling (fan auto).
OPTION 25 — NUMBER OF PROGRAMMABLE PERI-

ODS PER DAY  — This selection allows the installer to con-

figure the thermostat for two or four periods per day. This selec-

OPTION 26 — MINIMUM COOLING SET POINT — This

selection allows the installer to configure the minimum cooling

set point that the user is allowed to set. The range takes into

account the value of the adjustable deadband Option 11. The

range is 50 to 90 F (10 to 32.2 C) plus the deadband. The default

is 55 F (12.8 C) (based on the adjustable deadband default of 5 F

or 2.8 C).
OPTION 27 — MAXIMUM HEATING SET POINT — This

selection allows the installer to configure the maximum heating

set point. The range is based on the adjustable deadband value

Option 11. The range is 50 F to 90 F (10 to 32.2 C) minus the

deadband.

The default is 85 F (29.4 C) (based on the adjustable dead-

band default of 5 F or 2.8 C).
