adjustable boost overrun time of up to 15mins).

9.0 Trouble Shooting
The MVHR unit is not running?
1. Check that the unit is connected to a 3amp fused spur as per the wiring
instructions.
2. Check that there is a live feed to the fused spur. This should only be completed
by a qualified electrician.
3. Check that the 3-amp fuse has not tripped/blown. This should only be completed
by a qualified electrician.
4. Check that all the spindles are in the full power position (fans can take a few
seconds to start up).
The system is constantly in Boost mode?
New houses can be quite damp with items drying out; this can cause the inbuilt
humidistat to activate. Turning the internal humidistat up to 100% RH will allow the unit
to switch back to trickle speed (This may take 15min depending on the boost over-run
setting which can be adjusted to 0min on the control panel to temporarily disable).
Remember to turn the humidity stat back to its factory set of 70% RH upon achieving
the commissioned and reset the boost over-run time, if required).
