FIGURE 27 - Maxitrol
Series 44 Components used
in Recirculation Air Gas
Control Option AG48
Option AG48 electronic modulation system is comprised of Maxitrol Series 44
controls for makeup air with recirculation. The low limit (20-60°F) and the
high limit (60-140°F) for control of discharge air temperature are set at the
amplifier. The space temperature is set at the remote selectrastat (55-90°F range)
located in the space. When the temperature is below the space temperature
setpoint, the control system operates the burner and/or the outside air damper
to automatically adjust the discharge air temperature within the maximum and
minimum limits set on the amplifier.
Service - ALL Gas Controls: Check all electrical connections. A qualified
service person should refer to the control manufacturer's literature for assis-
tance in identifying problems and determining the correct solution. None of
the controls have field replaceable parts. All components must be replaced
with identical replacement parts.
Option AG51 electronic modulation
system is comprised of the same
Maxitrol Series 44 controls as Option
AG48 plus a remote sensor/selector. FIGURE 28 - Option AG51
