The Summer Mode fan speed is a % of Continuous SPEED 2. Therefore care must be taken to set the Summer Mode fan speed
at a value that makes the actual fan speed greater than 14%.
e.g. Continuous SPEED 2 x Summer Mode fan speed = Actual fan speed. 50% x 50% = 25%, 50%x28%=14%.
If the actual fan speed between 1% & 14% the fan may not run and an Error will be shown.

17°C 35°C 25°C In order for the Summer By Pass to
operate the temperatures of both
the air being extracted from and
supplied to the property must be
above their individual thresholds. If the
temperature of the Supply air exceeds
that of the Extracted air the Summer
By Pass switches o to prevent the
warmer air being supplied directly to
the property.

Duct Heater Frost User Frost Selects sensor that controls Duct Heater
activity.
Frost (FRST) = Uses sensor on the to
atmosphere side of the heat cell and the
Frost Protection Threshold temperature
congured in SETUP3.

Atmosphere (OUTSIDE) airstream and
user congured Duct Heater threshold
temperature.

Duct Heater threshold -4°C 16°C 4°C Temperature at which duct heater will
turn on. This setting is only used in User
mode.
Frost mode:
During falling temperature scenarios duct heater will switch on at Frost threshold + 2°C switch o at the Frost Threshold.
During rising temperature scenarios duct heater will remain switched on between
Frost threshold and Frost threshold + 2°C + Hysteresis °C.
User mode:
During falling temperature scenarios duct heater will switch on below Duct Heater threshold.
During rising temperature scenarios duct heater will switch o above Duct Heater threshold + Hysteresis°C.
If the supply fan is set to run at a speed less than 25% Duct Heater will not turn on. This can be either by a congured speed eg
Setback SPEED1, holiday mode or Frost protection being active).
