I need the correct wiring from a Janitrol HPT 18-60 to a Honeywell RTHL3550. I have a heat pump with an emergency heat strip.

The Janitrol wiring is as follows:
Y=YELLOW
G=GREEN
R=RED
O=ORANGE
W2=WHITE
E=SILVER (GRAY)
C=BLUE
Need to know corresponding terminals on the Honeywell
they are as follows:
L=
AUX/E=
G=
O/B=
Y=
R=
Rc=
Thanks,
Dave from OBX

R=Red
Y=Yellow
G=Green
O/B=Orange
Aux/E=White & Silver

I'm surprised there is no "C" (common) terminal on the new stat.

I searched Honeywell's site for an RTHL 3550 without success. Are you sure the model # is correct?

There is no C on the Honeywell. If you Google Honeywell RTHL3550 with no space it will come up. Thanks
