DESCRIPTION
Do not short out terminals on gas valve or primary
control. Short or incorrect wiring may damage the
thermostat.
CAUTION
!
WARNING
!
The 50M58-289 is a replacement control for two-stage automatic
gas ignition controls employing a microprocessor to continually
monitor, analyze, and control the proper operation of the gas
burner and inducer. The 50M58-289 controls a multiple tapped
induction circulation blower.
Signals interpreted during continual surveillance of the two-
stage thermostat and flame sensing element initiate automatic
ignition of the burner, sensing of the flame, and system shutoff
during normal operation.
The control incorporates system fault analysis for quick gas
flow shutoff, coupled with automatic ignition retry upon sensing
a fault correction.
