Approvals
The Micro2000 series controllers conform to:
• Electromagnetic emission and immunity requirements according
to standards EN55011 (CISPR11) and EN50082 for CE Marking and
C-Tick Labelling.

Installation

1. The Micro2000 should be mounted on DIN rail in cabinets
approved for switchgear or industrial control equipment. It
should be mounted in a dry and clean location, free of excess
vibration. Maximum terminal cable entry is 1.5mm² wire.
2. Wire in accordance with INNOTECH connection diagrams and
local bylaws or refer to your local distributor.
3. Connect the 240VAC supply to the correct terminals on the
controller, observing the correct polarity of the connections.
Connect the EARTH to the correct terminals on all units.
4. The maximum wire length between the control station and the
controller should not exceed 50 metres. The wiring between
these devices should not be run in parallel with conductors
carrying high current.
This product should only be installed by qualified personnel.
Fault Representation
1. If the Control Station display reads "HELP", this is due to a
communications error between the Controller and the Control
Station. Check the interconnecting 2 core screened cable
for continuity or short circuits. As a result of this failure the
controller will shutdown after 1 minute.
2. If the Control Station reads "SEN 1 FAIL", this is due to an open
circuit Sensor on Input 1. The fault occurs if an open circuit has
been detected at Input 1 for more than 20 seconds. As a result
of the failure, the controller will shut down. In this mode, the
fan can still be turned on (Vent Mode).
3. If the Control Station reads "SEN 2 FAIL", this is due to an open
circuit Sensor on Input 2. The fault occurs if an open circuit has
been detected at Input 2 for more than 20 seconds. As a result
of the failure, the controller will shut down. In this mode, the
fan can still be turned on (Vent Mode).
4. If the Control Station reads "FAIL", this is due to an open
circuit being detected on Input 1 & 2 at the same time. This is
a generic fault and can be used to shut the controller down
via an external relay (See wiring diagram for more details). As
a result of the failure, the controller will shut down and flash
"FAIL" on the display.
5. If the Control Station reads "no FLO", there has been no Flow
Verify Signal feedback from the Pump Interlock Module. The
fault will occur if a flow signal is not received within 30 seconds
of a Call signal.
Inputs
1. INPUT 1 - Zone 1 Thermistor (Innotech SENx) and External Start
Zone Change (Momentary Push Button) (Range 5-35°C)
2. INPUT 2 - Zone 2 Thermistor (Innotech SENx) and External Start
Zone Change (Momentary Push Button) (Range 5-35°C)
3. INPUT 3 - Pump Interlock Verify Signal. See Pump Interlock
Section for more details.
Multi-Purpose Inputs
There are two multipurpose inputs which are used as described
below.
The primary use of Input 2 is a 10kΩ Temperature sensor. If one sen-
sor is chosen in Parameter 12, the temperature sensed on input 2 is
used to control both zones (Day and Night). If two sensors are chosen
then Input 2 is used for the Day Zone and Input 1 for the Night Zone.
Both Inputs have multiple uses. If two sensors are chosen, both
inputs can be used as momentary push buttons as well as 10kΩ
Sensors. These push buttons are used as an external way to start the
controller as well as changing the zone to be controlled.
For example: a push button can be placed in the main bedroom of
the House/Apartment. This enables the user to start the controller
and change the zone without having to walk to the main Control
Station.
It will not stop the system if it is already running. It is only for
external start and changing the zone.
If one sensor is chosen in Parameter 12, then only Input 2 can use the
momentary push button start.
Outputs

Relay #3 Fan High (10A Relay. Common and Normally Open Contact)
Relay #4 Cool (10A Relay. Common and Normally Open Contact)
Relay #5 Night Zone (2A Relay. Common and Normally Open Contact)
Relay #6 Day Zone (2A Relay. Common and Normally Open Contact)
Relay #7 Heat (2A Relay. Common and Normally Open Contact)
Pump Interlock Operation
The M2K06 is equipped with a 3 wire pump interlock system. This
system should be used with a Micro2000 Pump Interlock Module
(M2KPI see Datasheet DS9.19).
When Compressor One is called for, the controller will send a "Call"
signal to the Pump Interlock Module. The Pump Interlock Module will
enable the pump and send back a "Verify" signal when flow has been
achieved. When the controller receives the "Verify" signal, it can
enable Compressor One.
Multiple M2K06 controllers connected in parallel use the same 3
wire Pump Interlock system and can be connected to the one Pump
Interlock Module (M2KPI). For further information, refer to the M2KPI
datasheet.

Common Connection
The "Fan" button is used to change the current fan
speed. The fan speed is indicated by 3 LEDs above the
button. If the controller is not running (Off), the Fan
button can be used to turn the Fan on only (Vent Mode).
The "Mode" button allows you to change the mode of
the controller between Auto, Heat and Cool.
The "Zone" Button allows you to change which zone is
to be Air Conditioned. Pressing the button toggles
between each of the zones. When "On" is selected in
Parameter 11 (Enable Both Zones), both zones can be
turned on at once.
When this occurs, the controller will use the average of
both sensors and the Day Setpoint to maintain
temperature. This only occurs when there are two
sensors fitted and/or two setpoints chosen.
This button has two selectable modes of operation. The
operation of the button can be changed by using
Parameter 9 to either Time Clock mode or Timer mode.
