Controls

HE2 MC3

Warning:

The

HE2 MC3

Panel and Evaporative Module contain live mains voltage and be isolated before com-

mencing installation and maintenance work.

Step 8 Controls

Terminals

Controls Wiring

Interlocks are connected to terminals 12-15 and provide a method of

switching the unit on or off, or overriding the normal operation of the

HE2

The interlocks are supplied pre-wired with a link as standard.

Thermostat/Humidistat Wiring:

When a stat is used, it should be wired to terminals 12 & 13.

If a control stat (N/C) and high-limit stat (N/C) are required, they would

be wired in series onto 12 & 13 and the unit will switch off in the event

that either contact is open.

Safety Interlock:

If fault indication is required on the microprocessor, for example where

the connection is an interlock for a water treatment product such as an

Ultra-Violet (UV) Steriliser, terminals 14 & 15 should be used. If the

contact is opened, the unit will not operate and a fault will be indicated.

Sensor / External Signal:

Terminals 16-19 are used to power a sensor and provide the

HE2 MC3

with temperature and humidity readings. If an external signal (i.e. from

a BMS) is to be used, it should be wired onto terminals 17 & 18 as

shown.

Common Fault Contact:

Terminals 20-22 are used to provide a common fault output, e.g. to

indicate to a BMS system that there is a fault preventing the system

from operating correctly. A Normally Open (N/O) contact, i.e. one

which will close in the event of a fault, or Normally Closed (N/C) con-

tact, i.e. one which will open in the event of a fault, is available as

required by wiring to the appropriate terminals. The

HE2 MC3

control

panel has the following fault modes: Safety Interlock Open, Water Inlet

Alarm, High Water Level, Service Due and PureFlo Ag+ Cartridge

Replacement Due. An explanation of each fault mode can be found in

the “

HE2

- Alarms and Fault Modes” section of this manual.
