Notes:
1 - Switch blue and red wires for 208V
operation.
2 - Connection of remote unit that does not
have a loop pump for slave operation.
3 - 24V Accessory relay (see SW2 - 3
for description of operation)
4 - The blk/wh and gray/wh wires are
removed when Aux Heat is installed
(ECM2 Only).
5 - DHW pump only in models with hot
water generation option.
6 - Air Flow Configuration Example: SW1
configured for dip 3 as low, dip 5 as
medium, and dip 7 as high speed
ECM2 fan.
7 - SW3-4 should be in the ON position
when using Premier 2 Electric Heat
control 17P514A01, and it should be in
the OFF position when using Premier
Electric Heat control 17P501A01.
8- When using thermostat TA32E12,
SW2 -8 should be in the "on" position.
When using 24VAC thermostats,
SW2-8 should be in the "off" position.
