IMPORTANT: Please note that the T and HT incorporate a switch on delay, which will start the fan after 2
minutes for the set timeout period. The delay is only activated via the LS and not via the pull-cord or humidity
sensor (if applicable). If the LS is switched off during the 2 minute period, the fan will remain off.
B. SETUP
WARNING: THE FAN AND ANCILLARY CONTROL EQUIPMENT MUST BE ISOLATED FROM
THE POWER SUPPLY DURING THE INSTALLATION / OR MAINTENANCE.
1. SELECTING THE CONSTANT TRICKLE (with Boost) OPTION
IMPORTANT: Constant Trickle with Boost option not available on P/E model. Please see note
below.
Link terminals 4 and 5 together for constant trickle with boost facility (fig. 14a).
2. SELECTING THE BOOST SPEED (T, HT, HTE and TM models)
This will determine the speed at which the fan will run when activated by either the Pull-cord/LS
line/Humidity/PIR.
The speed is factory set to Normal 63m3/h.
i.
Link terminals 2 and 3 (fig. 14a) for Normal (63m3/h) boost speed.
ii.
Link terminals 1 and 3 (fig. 14a) for High (84m3/h) boost speed.
IMPORTANT: Do not link across terminals 1 and 2.
The SOLO Plus P/E models do not have the ability to switch from 'constant trickle' to Normal or High speed
Boost. The fan can switch from Off to either Trickle, Normal or High speed (fig. 14b). For Constant Trickle,
Normal or High speed (with no boost option), switch the Pull-cord (P model only) into the On position and cut the
string.
3. TIMER ADJUSTMENT (T, HT, HTE and TM models)
The overrun time period is factory set to 15 minutes. The overrun time period may be adjusted from 5-30
minutes by altering the adjuster on the control PCB.
i.
To REDUCE the operating time, turn the adjuster [T] (fig 14a) ANTI-CLOCKWISE.
ii.
To INCREASE the operating time, turn the adjuster [T] (fig 14a) CLOCKWISE.
DELAY TIMER (DT - fig 14a): The timer function on the T and HT(E) also incorporate a switch on delay that
can be activated by removing the jumper header as shown in figure 14a, (referenced DT). Once activated, the
fan will not operate unless the LS has been activated for more than 1-4 minutes. The delay is only activated via
the LS and not via the pull-cord or humidity sensor (if applicable). If the LS is switched off during the 1-4 minute
period, the fan will remain off.
4. HUMIDITY ADJUSTMENT (HT/HTE model)
The fan's Humidity Set-Point is factory set to switch the fan on at 72%RH.
i.
To LOWER the Set-Point, turn the Humidity Adjuster [RH] (fig 14a) 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 [RH] (fig 14a) CLOCKWISE. This makes the fan less
sensitive to RH%, i.e. the fan will come on at a higher RH%.
C. WIRING.
WARNING: THE FAN AND ANCILLARY CONTROL EQUIPMENT MUST BE ISOLATED FROM
THE POWER SUPPLY DURING THE INSTALLATION / OR MAINTENANCE.
Use 0.75mm
1. Select and follow the appropriate wiring diagram (fig. 15-16).
2. It maybe necessary to feed the mains cable around between the outside of the Base Housing [C] and the Skirt
[H] to prevent the cable from being trapped.
3. Check all connections have been made correctly and ensure all terminal connections and cable clamps are
securely fastened.
4. Ensure the impeller rotates and is free from obstructions.
