| + | === Lounge ==== |
| + | |
| + | There is a wall mount A/C unit that is sort of old and may contain mold in the lounge. |
| + | |
| + | === Shop === |
| + | |
| + | There is a heat pump / air handler cooling system mounted on the ceiling and roof. |
| + | |
| + | 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. |

| + | === Upstairs === |
| + | |
| + | There is an AC unit in the comms/hvac closet upstairs near the side stairs. TBD documenting that. |
