• Restricted Mode (compressor heat only) – Once
enabled an outdoor temperature lockout can be set
to disable compressor heating operation. When the
outdoor temperature falls below the compressor
heat lockout the system will operate on auxiliary
heat source only. At any temperature above the
compressor heat lockout the system will operate
the same as non-restricted mode, heat pump or
auxiliary heat would be allowed based on system
load value. Once the compressor heat is locked out,
the outdoor temperature must rise at least 4° above
the compressor heat lockout setting before allowing
compressor heat again.

• Restricted Mode (compressor and auxiliary heat) –
Once enabled an outdoor temperature lockout can be
set to disable compressor heating below and disallow
auxiliary heat operation above. When the outdoor
temperature is above the auxiliary heat lockout,
only compressor heat is allowed. When the outdoor
temperature falls below the compressor heat lockout,
only auxiliary heat is allowed. When the outdoor
temperature is between the compressor heat lockout
and auxiliary heat lockout the system will operate the
same as non-restricted mode, heat pump or auxiliary
heat is allowed based on system load value. There is
a 10° minimum dead band between the compressor
heat lockout and auxiliary heat lockout. Once the
compressor heat or auxiliary heat is locked out,
the outdoor temperature must rise or fall at least 4°
above or below the lockout setting before allowing
compressor or auxiliary heat again.

7.5 Lockouts
The 824 has the following lockouts. AN OUTDOOR
TEMPERATURE SENSOR MUST BE ENABLED FOR
LOCKOUT SETTINGS TO BE AVAILABLE.
Lockouts can
be enabled in Installer Setup>Lockout Settings.
• Auxiliary Heat Lockout – Once enabled, select an
outdoor temperature which disables auxiliary heat
anytime the outdoor temperature is above the selected
temperature. Compressor heat will be allowed.
• Compressor Lockout - Once enabled, select an
outdoor temperature which disables compressor
heat anytime the outdoor temperature is below the
selected temperature. Indoor heat will be allowed.
NOTE: If enabling Auxiliary Heat Lockout and
Compressor Heat Lockout there is a minimum 10°
dead band between the two settings.
• Defrost Heater Balance Point (W1) – Once enabled,
select an outdoor temperature which disables all
electric heat during defrost above the selected
temperature.
• Defrost Heater Balance Point (W2) – Once enabled,
select an outdoor temperature which disables 2nd
and 3rd stages of electric heat during defrost above
the selected temperature.
• Defrost Heater Balance Point (W3) – Once enabled,
select an outdoor temperature which disables 3rd
stage of electric heat during defrost above the
selected temperature.
• Compressor Cooling 1st Stage Lockout – Once
enabled, select an outdoor temperature which forces
2nd stage cooling operation.
• Compressor Heating 1st Stage Lockout – Once
enabled, select an outdoor temperature which forces
2nd stage compressor heating operation.
