i.
To REDUCE the operating time, turn the timer adjuster ANTI-CLOCKWISE.
ii.
To INCREASE the operating time, turn the timer adjuster CLOCKWISE.
4. RELATIVE HUMIDITY ADJUSTMENT (HTP model only)
NOTE:- On installation it is possible that the humidity controller will run continuously until
it has acclimatized to the environment.
The fan's relative humidity (RH) set-point is factory set to switch the fan on at about
75%RH. This set point can be raised or lowered by altering the upper adjuster of the two
on the PCB (fig.4 & 7).
i.
To LOWER the set-point, turn the humidity adjuster (fig.4 & 7 ) ANTI-CLOCKWISE. This
makes the fan more sensitive to RH, i.e. the fan will come on at a lower RH.
ii.
To RAISE the set-point, turn the humidity adjuster (fig.4 & 7) CLOCKWISE. This makes
the fan less sensitive to RH, i.e. the fan will come on at a higher RH.
The fan will continue to run at boost after the RH has dropped below the set point for the
time period set by the timer adjustment (see 3. TIMER ADJUSTMENT, above)
C. WIRING.
