Approvals
The Micro2000 series controllers conform to the to the requirements
per European Consortium Standards EN55011:1998 (Emissions),
Class B, Group 1, EN50082-1:1997, EN61000-4-2 (Electrostatic
Discharge), EN61000-4-3 (Radiated RF Immunity), ENV50204
(Radiated RF Immunity-Keyed Carrier), EN61000-4-4 (Electrically
Fast Transients 1kV), EN61000-4-5 (Surge), EN61000-4-6 (Conducted
RF Immunity), ICE1000-4-11 (Main Variations) for purposes of
CE certification and also the requirements of the Australian/
New Zealand standard AS/NZS 2064 1/2:1992 Class B Group 1 for
purposes of C-Tick certification.

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 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 FAIL", this is due to an open
circuit room Temperature Detector. The fault occurs if an open
circuit has been detected for more than 20 seconds. As a result
of the failure, the Controller will shut down.
3. 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 Temperature Sensor Input: (Range 5 - 35°C.) This input
is used to read the current temperature.
2. INPUT 2 - Selectable Dry Contact Digital Input:
Using Parameter 12, Input 2 can be either be a Door Switch
Input, AC Fault Input, a External Disable Input, or External
Enable Input.
Door Switch
If "Door" is selected in Parameter 12 and Input 2 is "ON" for
the time set in Parameter 13 (Door Open Time), the Micro2000
will display "Door" and will go into Standby Mode. In Standby
mode the Dead Band is increased by the adjustable value in
Parameter 14 (Door Reset Dead Band). If Parameter 14 reads
10°C, there is a 5°C dead band either side of the setpoint.
However if Parameter 14 is set to 0 (Off) then the Micro2000 will
shutdown all outputs. After the door is closed the Micro2000 will
continue to operate in is previous state.
AC Fault
If "AC" is selected in Parameter 12 and Input 2 is "ON" the
Micro2000 will display "AC FAIL" and continue to operate in it's
current mode. After the fault is rectified, the display will revert
back to its previous state.
External Disable
If "dIS" is selected in Parameter 12 and Input 2 is "ON" the
Micro2000 will shut down all outputs and display "OFF". After
the disable input is removed, the Micro2000 will continue to
operate in its previous state.
External Enable
If "EnAb" is selected in Parameter 12 then Input 2 is used as an
External Enable Switch. It's operation is the same as the On/
Off button on the front panel. See the Push Buttons section for
more details.
3. INPUT 3 - Pump Interlock Verify Signal. See Pump Interlock
Section for more details.
All Digital Inputs have a 5 second delay before they are
registered.
Outputs
Relay #1 Fan Low (10A Relay. Common and Normally Open Contact)
Relay #2 Fan Mid (10A Relay. Common and Normally Open Contact)
Relay #3 Fan High (10A Relay. Common and Normally Open Contact)
Relay #4 Cool (10A Relay. Common and Normally Open Contact)
Relay #5 Heat (2A Relay. Common and Normally Open Contact)
Pump Interlock Operation
The M2K08 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 M2K08 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.
This button has two selectable modes of operation. The
operation of the button can be changed by using
Parameter 10 to either Time Clock mode or Timer mode.
