HONEYWELL AM (HAM) 0-10VDC MOD-
ULE INSTALLATION INSTRUCTIONS
(Requires Kit# 550001314)
The Honeywell AM (HAM) kit allows the boiler’s mod-
ulation to be controlled by an external 0-10vdc signal
supplied by most modulating multiple boiler controls.
WARNING
This document must only be used by a quali-
fied heating installer or service technician. Read
all instructions, including this Supplement, the
Boiler Installation Manual (p/n# 240006103), the
Control Manual and Operating Instructions (P/
N# 240006104), and the Parameter Guide (P/N#
240006105), before installing. Perform steps in
the order given. Failure to comply could result
in severe personal injury, death or substantial
property damage.
IMPORTANT: The alarm contacts of the HAM mod-
ule are rated for 2 amps at 120 vac. All hard lockout
conditions of the boiler control module will cause an
alarm. Soft lockouts will not cause an alarm.
In addition to mounting and wiring the HAM module
to each boiler operated by the multiple boiler con-
troller, you will need to program the boiler control
module of each boiler to accept a 0-10vdc input sig-
nal, as described in these instructions.
IMPORTANT: Installation must comply with local re-
quirements and with the National Fuel Gas Code,
ANSI Z223.1 for U.S. installations or CSA B149.1 or
B149.2 for Canadian installations.
