Compressor and Crankcase Heater P/N's by Voltage on MAPS ® IV Models
Modulating Cooling -
MAPS ® IV Models
MAPS ® IV units are equipped with a modulating capacity compressor and a digital con-
troller to provide cooling modulation. The digital controller in the control compartment
(See FIGURE 1, page 5) is the electronic interface between the compressor and the
system controller. The compressor controller is connected to the unit controller to pro-
vide protection and diagnostics for modulating compressor operation.
After a compressor shutdown, a two-minute anti-short cycle timer in the compressor
controller delays the compressor restart. The unit controller has a five-minute compres-
sor on/off time. The delay times are concurrent so total delay time is five minutes.
