MULTISTACK USER FRIENDLY CONTROLLER
COMPUTER CONTROL
A computer control with 5.7” touch panel and monitoring system runs the Multistack chiller bank and schedules each
compressor off or on and capacity control of stages, depending on the changing cooling load. The system continuously
and comprehensively monitors total operating conditions of all refrigeration circuits of the chiller bank. Maximum 32
compressors can be monitored.
TEMPERATURE CONTROL
Multistack chiller is controlled either by entering water temperature or leaving water temperature. For variable water flow
(VWF) models, controller will use leaving chilled water temperature to operate.
SYSTEM DATA AND VARIABLES DISPLAY
A comprehensive range of Chiller system / slave data and variable settings can be selected from the Multistack
computerised monitoring system for display on the menu.

COMPRESSOR SEQUENCE
MV6 accumulate running hours of each compressor and hence establish working sequence. A standby compressor with
least working hours will be activated once call when loading. Same as a compressor with most working hours will be
stopped once unloading.
LOAD PROFILE
Cooling capacity of Multistack chiller is divided into 10 sections from 0% to 100%. Controller accumulates the working
time of the chiller in each section and each compressor automatically.
FAULT REVIEW
It displays the last 60-recorded faults identified with time and date, system temperatures, individual refrigeration circuit
temperatures and type of abnormal conditions.
PASSWORD
For service and maintenance, only personnel with appropriate password can access and modify the controller.
INDIVIDUAL REFRIGERATION SYSTEM MONITORING
Conditions such as high pressure, low pressure, refrigerant temperature, leaving chilled water temperature of individual
refrigeration circuits and system conditions are monitored.

REMOTE CONTROL & MONITORING (RCM)- OPTIONAL
MV6 is fitted with RS485 serial port, which enables remote control monitoring (RCM) :
1. Connect to PC Under software optional supplied by Multistack, and compatible with Window version, remote control
is built to monitor chiller. Maximum communication cable length is 1200m.
2. MV6 is opened to ASCII agreement and communicated with BAS.
3. With Ethernet-card and a unique IP address, customer can built up its data transmission system via internet… of
which is optionally supplied by Multistack.
