7. Cool Recover
Y/N (default N) (up button to change, mode to enter)
This mode provides ventilation when house is warm and air is cooler outside. It is
manual, as there are times when house has been heated, but is cool outside, hence the
limit if the attic temperature is below 15°C.
If 'Y': When the house (T
attic temperature ('O/side Ref Temp': T
increases. Fan speed is proportional over the temperature difference to 3°C to cool
the house down (the 3°C is changeable using 'Heat Reco P/band'). This will not
operate if attic temp is below 15°C (changeable using 'O/side Ref Temp': T
8. Filter Timer
on (default Y) - Sets a timer to count how many days since last filter change.
9. Filter Alm days
(default 240) range 150-240 - Filter Alarm - Display will flash 'Swap Fltr'
when the filter is due to be changed (see c2 on p4 to reset).
10. I/side Ref Temp
- Hall reference temperature
20° C
11. O/side Ref Temp
- Attic reference temperature
15°C
12. O/side De g
offse- Attic Degree Offset (default 0) Provides site calibration of attic temp
display if required. eg use -2 if controller reading 2°C too high.
13. I/side De g
Offse- Hall Degree Offset (default 0) Provides site calibration of house display if
required. eg use -2 if controller reading 2°C too high.
14. Heat P/band
(default 3°) - range 1-7°C.
At a proportional band of 3°C, heater will start to operate at attic temp 15°C and is fully
on when temperature gets down to 12°C. A smaller proportional band will bring heater
on over a smaller temperature range.
15. Heat Reco P/band
- With proportional band of 3°C, the fan starts to speed up when the attic is 1°C warmer
than the house. Fan speed is at max when the attic temperature gets to 3°C above
house temperature (provided the house is below the reference temperature T
default 20°C).
16. Cool Reco P/band
- With proportional band of 3°C, the fan starts to speed up when the attic is 1°C cooler
than the house and is at maximum speed when the attic temperature gets to 3°C
below the house temperature (provided house is above the reference temperature T
(default 20°C), cool recovery is enabled and attic is above T
17. Summ Temp s/down
the house is hot and the attic is very hot (T
decreases again.
18. Factor y Reset
(default N) (up button to change,
mode to enter) Resets everything (including
heater on & off times - back to 7pm-7am).
