First post - Hope you guys can help.

I'm finishing up a large remodelling job on my house, and I'm having trouble installing a Honeywell 9320wifi5003 wifi thermostat on my hvac system.

I have a Spacepack air handler/outside unit (condensor) for cooling and a condensing boiler/radiators with Taco SR504 switching relay for heat (4 zones). Have 5 wires between thermostat and Spacepack air handler. All other wiring is accessible. Need a wiring diagram because I'm struggling to get everything to play nice together. Can anyone help? Thank you

Hey, wait a minute.
