UL and CSA approval does not apply to 230VAC operations.
WARNING: This equipment is a Class B digital apparatus which complies with the Radio
Interference Regulations, CRC c.1374.
CAUTION: Published load ratings assume that no control be required to handle inrush
current more often than once in 15 seconds. The use of control switches, solenoids, relays,
etc. which chatter will lead to premature failure. It is important to run through a test
operation (with fuel shut off) following the tripping of a circuit breaker, a blown fuse, or
any instance of chattering of any external current consuming devices.
WARNING: Selection of programer and amplifier type for a particular application should
be made by a competent professional, such as a Boiler/Burner technician licensed by a state
or government agency, engineering personnel of the burner, boiler or furnace manufacturer
(OEM) or in the performance of duties based on the information from the OEM.
WARNING: This equipment generates and can radiate radio frequency energy, and if not
installed and used in accordance with the instruction manual may cause interference to
radio communications. It has been tested and found to comply with the limits for a Class A
computing device pursuant to Subpart J of part 15 of FCC Rules, which are designed to pro-
vide reasonable protection against such interference when operated in a commercial envi-
ronment. Operation of this equipment in a residential area is likely to cause interference in
which case the user, at his own expense, will be equipped to take whatever measures that
may be required to correct the problem.
In order for the MicroM to gather and retain statistical and historic data such as burner
hours, burner cycles, system hours and average flame signal, it is necessary that Terminal 1
be powered at all times. Removing power from Terminal 1 at the end of the firing cycle
causes all data gathered during the previous 16 hours or last 9 cycles to be lost. For conver-
sions or upgrades from older TFM or M-Series II controls that use MART1 amplifiers, it is
necessary that Terminal 1 be directly powered with 120 VAC.
