CORRIGO C10-LON

INSTRUCTION

Corrigo C10-LON is a controller primarily intended

for controlling air handling units. It can easily be

adapted to suit different types of units.

Corrigo C10-LON has built-in capability for LON

communication. See separate LON interface manual.

Corrigo C10-LON has three 0...10 V DC control outputs

in sequence for controlling for example heating / heat

exchanger / cooling.

It has a number of functions and possibilities, such as

DX-cooling in one or two steps, outdoor temperature

compensation, fire damper exercise, control and

monitoring of fans and circulation pump, free cooling,

heat-exhanger efficiency calculation etc.

Corrigo C10-LON can also receive and handle a number

of alarms such as fan and filter alarm, smoke alarm,

chiller alarm, heat-exchanger alarm and has a free relay

output for total alarm.

Corrigo C10-LON has a year-base real-time clock,

week-scheduler , holiday calendar, holiday periods and

automatic normal time/daylight saving time change-over.

Installation

Mount the unit on a DIN rail in a cabinet or separate

enclosure.

For mounting in the cabinet front, use mounting kit FMC.

Degree of protection IP20

Ambient temperature 0...50°C

Wiring

Supply voltage

Terminals 42 and 43: 24 V AC, ±15%, 50/60 Hz.

Sensors AI3...AI8

Use PT1000 sensors. (See data sheet 4-150).

The choice of which sensors to connect is determined by

the choice of functions. The table, fig 3 can be used as

an aid in determining which sensors to install.

Connect the sensors according to the terminal schema-

tics on page 6.

N.B. All AI-inputs must refer to the signal neutral termin-

als for AI-inputs (terminals 24, 27, 30, 33).

AI4 has different functions depending on settings.

1. Efficiency calculation - exhaust air sensor.

2. Liquid-connected heat exchanger - limiting sensor in

the exchanger circulation system.

3. External setpoint. Input for setpoint signal.

These functions are mutually exclusive.

Only one of them may be chosen.

AI8 is, depending on setting, used for:

1. Frost protection sensor for applications with water

heated heater.

2. High temperature limiting switch for applications with

electrical heater.

When used for high temperature limiting switch it must be

connected to a free contact closing on alarm.

Fan supervision,

supply air fan, exhaust air fan AI1, AI2

Connect AI1 and AI2 to free contacts that open when the

fans stop.

Either in form of pressure switches monitoring the

pressure over each fan or as free contacts in the fan

motor relays.

N.B. Since these signals control vital functions they must

be connected for the unit to work as intended.

Digital inputs DI1...DI8

The digital inputs DI1...DI8 must refer to terminal 22.

N.B. Terminal 22 must not be connected to any other

terminals but should only be used as reference for units

connected to DI1...DI8.

The inputs may only be connected to potential free

contacts.

Closed contact activates alarm or function.

Unused inputs are to be left open.

DI1 Input for filter guards

DI2 Input for circulation pump indication.

Must be connected for systems with water heating.

DI3 Input for chiller alarm

DI4 Input for rotation sentinel or ice build-up sentinel for

heat exchanger.

DI5 Input for smoke alarm.

DI6 Input for fire damper end-position indication, external

alarm or external switches ”not in Auto position”.

(See textblock on DO6/DI6 on page 6).

DI7 Input for start of extended running time for single

speed fan systems or high speed for two speed fan

systems.

DI8 Input for start of extended running time at low speed

for two speed fan systems

DI7 and DI8 should, depending on settings, either be

wired to a momentarily closing pushbutton or to, for

example, a timer.

If DI7 and DI8 are both closed at the same time the unit is

shut down.

If a separate handswitch for setting the running mode is

installed it should be wired according to figure 1 or 2.

IMPORTANT: Read these

instructions before installation

and wiring of the product.
