Local control of AD10 Appliance Module

[Williams Christopher C <CCWILLIAMS@xxxxxxx>]

I am after some advice on AD10s

I would like to use an AD10 to control our HRV (Heat Recovery
and Ventilation) system.  Currently it is operated be pulling a cord
switch in the shower room or by switching the switch on the cooker hood.
What I want to be able to do (initially) is have it turn off at a set
time so that it isn't left running all day. (Makes quite a noise outside
:( ).

My question regards using non-momentary switches to control the
AD10 locally.  As I understand it if an appliance module is off and the
switch is in the on position it is necessary to cycle the switch off-on
to activate the module.  I can handle this.  What happens if the module
is on and the switch is off?
Can you cycle the switch on-off?

Additionally how would you connect two switches?  I can see that
this is more of a problem. Currently the switches are in parallel so if
either switch is on then the unit runs at full speed. This in itself is
not ideal, but if I can switch the unit off with X10 it will help.

Is it possible to get momentary action pull switches?

Finally, am I right in thinking that the AD10 has a relay and no
leakage current?  The reason I ask is that the HRV unit has a speed
controller which keeps the motors just ticking over 24hrs a day and the
switches override this by applying full mains to the motors without
disconnecting the controller.

And really finally could I use an LD10 to control the motors
(i.e. adjust their speed with X10)??  They are approx. 40W each.

Cheers,

Chris Williams
