Pressed it and arrow blinked off
Turned back to occupied
HVAC Technician: BillyHvac, Journeyman HVAC Tech replied 2 years ago
Ok,
if it did NOT start...it is locked.
There is a way to bypass for direct cooling but involves removing the top section of the thermostat to where we see the wires....if you are game for that let me know...
Ask Your Own HVAC Question
Customer reply replied 2 years ago
How long?
Difficulty level?
HVAC Technician: BillyHvac, Journeyman HVAC Tech replied 2 years ago
quick...and easy...
we remove the top section of the thermostat...allen set screw on bottom.
Top section comes off to expose the wires....these are low voltage wires we can touch.
Take wire from R (red) wire from G (green) and wire from Y (yellow)
Twist those 3 wires together and you have cooling....UNLESS something is wrong with the equipment and not thermostat

Red yellow green twisted together
No response
From over head blower vents in dining area
But AC in common areas not working
HVAC Technician: BillyHvac, Journeyman HVAC Tech replied 2 years ago
The blower is running but not cool or nothing in this area working?

I'm a "maintenance director"@ an Alzheimer's special care facility
My background is in carpentry 20yrs
But this commercial HVAC stuff is completely foreign to me
HVAC Technician: BillyHvac, Journeyman HVAC Tech replied 2 years ago
I understand.
Unfortunately the issue appears to be the equipment...
Red green and yellow send direct signal for cool. If blower is is attic...I would check it for a plugged drain....this trips a switch that interrupts power to the thermostat.
After that we are talking about a voltmeter with step to step troubleshooting
Ask Your Own HVAC Question
Customer reply replied 2 years ago
Dude I don't even think blower is running
In the dining area where I am the overhead blower vents are emitting nothing not even warm air
But the vents out in other areas of the building seem to be blowing cool air
I have thermostats three I think
I know this is not a substation
Because it is labeled on my map diagram as T stat
HVAC Technician: BillyHvac, Journeyman HVAC Tech replied 2 years ago
If the drain on the blower unit is plugged...it would turn off the signal till drain cleared.
If you choose to move forward with a voltmeter just let me know.
