INSTALLATION

CM2K module is installed on the wall or on hard surface in closed dry room.

According the picture below, drill 3 holes 6 mm x 35-45 mm.

Insert 3 dowels into drilled holes and install screw into upper dowel with ca. 4 mm discance from the wall.

Remove lower cover, hang the module on the upper screw, install lower screws to the mounting holes in the module and in

the wall. Fasten the screws to secure the module to the wall.

Room corrector CSK

Note:

Room corrector CSK is NOT in delivery package.

With CM2K module is posible to use only CSK room corrector from producer Centrometal.

Maximum of two room correctors can be connected, one for each circuit.

Outdoor sensor OVT is NOT in delivery package.

At certain boilers outdoor sensor is in standard delivery and at some boilers it must be separately ordered.

in EKO-CKS Multi Plus boilers, additional equipment

(CM2K included) must be connected to free UTP connector

on the regulation box or any free UTP connector on the any

PCB in the regulation box (installed PCBs depends of the

installed boiler equipment)

Connecting more CM2K modules

Maximum up to 4 modules can be connected. Connection is done by UTP cables. UTP input/output 1 or UTP input/output 2

can be used (they both have same function, free connector is used for connection of next module or for connection of other

additional equipment).

If there are more than 1 CM2K installed, in every module is necessary to set device address (0-4). Address is set by SW

switches on the PCB of the module (below casing cover of the connection clamps). Order of connection is not important,

circuit number is defined by module address with SW switches (every module must have different address, i.e. two devices

can’t have same address).

*If vacuum turbine CVT is connected, it must be connected last in order

Connection is done with UTP cables. Every additional equipment device has 2 UTP connectors (except vacuum turbine

CVT). Both UTP connector have same function. Devices can be connected in any order except vacuum turbine, which

must be always last in order because it has only 1 UTP connector.

symbols

- status - indicates CM2K status; connection with the boiler is ok, boiler is connected to the power supply and main

switch is on - doesn’t mean that CM2K is connected to the power supply (230V)

- for pumps and actuators working CM2K power supply (230V) must be connected

- pump - indicates working of the pump (LED ON = pump works / LED OFF = pump doesn’t work)

- actuator - close (LED ON = actuator closes / LED OFF = actuator doesn’t work)

- actuator - open (LED ON = actuator opens / LED OFF = actuator doesn’t work)

NOTE: actuator open and actuator close can’t work at the same time
