These are some very vague and poorly collated notes about that:
These are some very vague and poorly collated notes about that:
heat pump stat - but we aren't using the heat pump for heating, so we
don't even need the fancy board since it's for defrost. we use it when
we're cooling only. Right now, the wire from the roof is wired to make
it so when power is on (7,9,11) PP1-1 - it runs all the time. There is
no relay control of it that's active. the red wire in the control wire
will throw a relay on and off to control the heat pump.
but, we don't need to use the heat mode of the unit and it's not wired
upstairs for it at the moment, so we should set up the filtrete like so -
take off silver jumper
use RC and Y. (normal cooling, not heat pump cooling - the transformer
is ganged right to the relay up top).
thin red wire on the transformer goes to RC
thick red wire from the roof goes to Y
blue and white should be stuck together like they are.
we also need to put the air handler/fan unit on the coil that hangs down
(big tan thing) run always if the heat pump is on, since it will ice up
otherwise. However, it's also useful when things aren't in cooling mode
for running some air from outside to the shop, so we want a switch that
can manually trigger the relay that will be controlling the air handler.
