Early Start
OF
On / OF
• On: Heating or cooling starts in advance (as determined by the controller) so
that the desired temperature is attained at the set times.
• OF (Off): Heating or cooling starts at the set times.
NOTE: Early Start applies for periods 1 and 3 (P1 and P3) only. When this feature is
enabled, heating or cooling will start in advance of the set time for P1 and P3 but will
start at the set time for P2 and P4.

Automatic daylight
savings adjustment
OF
OF / 1 / 2
• OF (Off): The function is deactivated.
• 1 : The controller switches to daylight savings time on the first Sunday of April
and to normal time on the last Sunday of October.
• 2 : The controller switches to daylight savings time on the second Sunday of
March and to normal time on the first Sunday of November.

Temperature format
°C
°C / °F
Select the temperature display format.
5
Balance point low
(note 1)
-10°C
(14°F)
-30 to 10°C
(-22 to 50°F)
Set the bP L limit (see section 4.2).
NOTE: Lower bP L below its minimum (- -) if you do not wish to use this function.
6
Balance point high
(note 1)
5°C
(41°F)
-5 to 30°C
(23 to 86°F)
Set the bP H limit (see section 4.2).
NOTE: Raise bP H above its maximum (- -) if you do not wish to use this function.
7
Defrost point
(note 1)
10°C
(50°F)
-10 to 15°C
(14 to 59°F)
Set the defrost point temperature (see section 4.3).
NOTE: Raise the defrost point above its maximum (- -) if you do not wish to use this
function.
8
Installation type
(note 1)
Ad
Ad / nr
Set according to the type of heat pump installation (see section 4.4).
• Ad (add-on): Use this setting when the indoor coils are located downstream of
the auxiliary heat source. This is generally the case for add-on installations.
• nr (normal): Select this setting when the indoor coils are located upstream of
the auxiliary heat source. This is generally the case for new installations.
9
Auxiliary interstage
delay (note 1)
30 min.
5 to 90 min.
Set the interstage delay for the auxiliary stage (see section 4.5).
10
Low temperature
limit (note 2)
- -
(disabled)
-10 to 20°C
(14 to 68°F)
Set the low temperature limit of the plenum (see section 4.6).
NOTE: The function is disabled when LLMT is set below its minimum (- -).
11
High temperature
limit (note 2)
- -
(disabled)
30 to 90°C
(86 to 194°F)
Set the high temperature limit of the plenum (see section 4.6).
NOTE: The function is disabled if HLMT is set above its maximum (- -).
12
Cycles per hour
4
2 to 6
Select the number of heating/cooling cycles per hour. For optimal heating control, use
the setting that matches your system as follows: 3=20 min (hot water, 90%+ high-
efficiency furnace), 4=15 min (gas or oil), 5=12 min (gas or oil), 6=10 min (electric).
13
Heat type
EL
GA / EL
This setting determines the fan operation in automatic mode when the system is in
heating mode.
• EL (electric heating): The fan starts when heating starts and stops when
heating stops.
• GA (gas or oil heating): The fan starts when the temperature inside the plenum
rises above the Fan Limit (see item 14) and stops when the temperature drops
12°C below the Fan Limit.
NOTE: The fan will not start if the plenum
temperature sensor is not connected to the controller.
14
Fan limit
80°C
(176°F)
38 to 90°C
(100 to
194°F)
This parameter is available only when gas heating is selected (see item 13).
WARNING: FLMT can be used in parallel with an UL353-approved device but they do
not replace such device.
NOTE: The fan will not start if you raise FLMT above its maximum (--).
15
Smart Fan
OF
On / OF
• On: Smart Fan is On (see section 4.7).
• OF: Smart Fan is Off.
16
Temperature
setback
0°C
(0°F)
0 to 9°C
(0 to 16°F)
Set the amount of temperature setback when the controller is placed in Unoccupied
mode (see user guide).
17
Humidifier
operating mode
HE
Co / HE / Fn
• Co (conventional): The humidifier will operate if the humidity is too low. If the
fan is not already On, it will turn On at the same time as the humidifier.
• HE (heat): The humidifier can operate only when heating is activated.
• Fn (fan): The humidifier can operate as long as the fan is running, whether
heating is activated or not.
NOTE: The humidifier is disabled when cooling is activated.
18
Dehumidifier type
Co
Co / AE / dr
Set according to the type of dehumidifier used.
• Co (conventional): Select this setting when using a dehumidifier (except an air
exchanger) or when you do not wish to dehumidify.
• AE (air exchanger): Select this setting when using an air exchanger (see
section 4.10).
• dr (droop): Select this setting to dehumidify by droop (see section 4.9).
19
Minimum air
exchange time
0
0 - 60 min.
This parameter is available only if the controller is configured for using an air
exchanger (see item 18). Use it to set the minimum air exchange time (see user
guide).
Note 1: Parameters 5 to 9 are not available when the controller is configured for HVAC or 1H1C, 2H2C or 3H3C heat pump.
Note 2: Parameters 10 and 11 are not available when the controller is configured for heat pump.
