3. MHRC Start Up Screens
(MCS-MAGNUM controller sensors are in manual mode for purpose of display)
The MCS-MAGNUM controller is a state computer, that is, decisions are made based upon setpoints, timers and
sensor inputs, the controller moves from one state to another. The controller will change states to ensure the
proper functioning of the MHRC package.
As we review the various states, we must remember the MHRC package consists of a number of different parts:
the compressors, evaporators and condensers plus the mode of operation.
The following sequence occurs at Power Up:
3.1. MHRC OPERATIONAL
3.2. MHRC UNIT STATUS – POWER UP
C TNK = COLD TANK TEMPERATURE
H TNK = HOT TANK TEMPERATURE
