Replacing Janitrol HPT 18-60 with Honeywell RTH2310

The wires coming from my Janitrol are: Y-Yellow, G-Green, R-Red, O-Orange, W2-White, E-Black, C-Blue

The New Honeywell slots are labeled: Rh, Rc, W, Y, G... Which of the current Janitrol wires goes in which slot?

Looks like you have the wrong honeywell

You need a honeywell that states its for 2H/1C
Meaning its for a heatpump
