This PID Controller can be used to control humidity or
temperature in various ventilation and air conditioning
system applications.
The serial link function allows the MMC to be fully
integrated into a networking system with all the advantages
of remote monitoring, alarms, logging, graphics and remote
setting of all control parameters. The MMC can work as a
fully stand-alone controller.
The controller can be configured to run in one of the
applications by simply selecting that application number.

2. Two Stage Temperature Controller
3. Three Stage Temperature Controller
4. Three Stage Room Temperature Reset Controller with
Heat Recovery
5. Three Stage Cascade Temperature Controller
6. Single Stage Temperature Controller
(24Vac Actuator Output)
7. Single Stage Humidity Controller
8. Two Stage Humidity Controller

10. Simple Two Stage Temperature Controller
11. Simple Three Stage Temperature Controller
The MMC is a Multi-loop Controller for use in district
heating schemes.
The controller incorporates three separate control loops, two
compensated and the other a constant temperature loop.
Up to 3 specific points are programmed for the
compensation graph. The MMC automatically joins up these
points to produce a user defined compensation curve. This
adjusts and calculates the required set value of the supply
temperature to the compensated system to match the
prevailing requirements.
The MMC has a self tuning function that allows each of the
3 control loops to have its proportional band, integral action
and derivative action values automatically tuned. Self tuning
can be carried out from the MMC keyboard or from
optional external momentary switches connected to it. Self
tuning maximises the efficiency of control loop operation.
FEATURES
• Serial link
• Can be programmed through its own keyboard
• Real Time Clock (RTC)
• Self tuning for each control loop, maximises efficiency
for each loop
The CZU is an Electronic Modulating Controller for the
control of terminal units or fan coils in air conditioning
systems serving small zones of buildings such as individual
offices and hotel bedrooms.
The range includes temperature sensors and actuators
for valve operation and associated two, three and four
port valves.
FEATURES
• Simple installation
• Three wire connection to actuators
• Optional auto changeover
• Minimal commissioning time
