Page 20: Over-Run Timer
6.12. OVER-RUN TIMER Operation: The over-run timer works when you alter the ‘Timer’ potentiometer, this will allow you to add an over-run of 0 to 15 minutes; the over-run function will operate for both remote enable and boost functions. If a 10 minute over-run is set then the remote enable will over-run for 10 minutes and the boost will over-run for 10 minutes. -
Page 21: Fan Speed Offset
6.13. FAN SPEED OFFSET Operation: The fan speed offset works when you alter the ‘Off-set Output 2’ potentiometer, this will allow you to alter the fan 2 output by +3V or -3V; this is limited by the minimum output 3V and maximum output 10V. -
Page 22: Maintenance
7. MAINTENANCE Before handling the ventilator, make sure it is disconnected from the mains supply even if it has previously been switched off. Prevent the possibility of anyone else connecting it while it is being worked on. The apparatus must be regularly inspected. These inspections should be carried out bearing in mind the ventilator’s working conditions, in order to avoid dirt or dust accumulating on the impeller, motor or back-draught shutter. -
