1 Introduction

DEVIreg™ Multi is 7 channel electronic programmable controller to be installed on

DIN-rail and supposed to be used for controlling electrical heating and cooling systems.
Every channel can be individually set up with three control modes –temperature sensor,
time proportional power regulation without sensor and manually on/off with time period.

Universal analog channels’ inputs can be selected via software between 8 types of temperature
sensors including NTC 15 kOhm at 25 °C. Controller has graphic LCD display, Modbus RS-485
opto-insulated serial interface and 110/230 V AC power supply.

DEVIreg™ Multi has 8 control relays – 2 sets of max. 10 A and 6 sets of max. 6 A; and among
them 4 sets NO and 4 sets NC/NO contacts. Relay control functions can be set up for heating
or cooling systems. Additionally, relay contacts are not connected to a voltage source inside
the controller, and can be used for control systems with any voltage up to 250 V AC.

In addition to 3 control modes, DEVIreg™ Multi has some special functions which can be
programmed for every channel: relay status – opened or closed for ‘Heating On’ mode,
channel activation or deactivation, sensor failure alarm, min. and max. temperature alarms,
cable failure monitoring, relay test, channel on/off, relay cycles’ calculator, etc.

Hardware of DEVIreg™ Multi is based on the Danfoss controller type MCX08M2,
art. no. 080G0307, but is customized with special software.

The product complies with the EN/IEC Standard “Automatic electrical controls for house­hold and similar use”:

• EN/IEC 60730-1 (general)

• EN/IEC 60730-2-9 (thermostat)

4 User Manual

4.1 Control modes overview

The DEVIreg™ Multi is 7 channels controller and every channel can be individually set up
with one from three control modes:

1. Single sensor control with temperature sensor - ‘1 Sensor’ mode or ‘1S’.

2. Time proportional power regulation – ‘Power Regulation’ mode or ‘PR’.

3. Manually On/Off control with time period – ‘MOn’/’MOf’ mode.

1S mode or Single sensor control

1S mode is control with temperature sensor and adjustable hysteresis. 1S control typically

can be used for Pipe heating, Ground Ice & Snow melting, Cold rooms’ protection, Comfort
Floor heating, Total heating and other applications with temperature control.
This control mode is similar to well-known DEVIreg™ 316 thermostat.

Universal analog channel’s inputs (AI) can be selected via software between 8 types of
temperature sensors including NTC 15 kOhm at 25°C.

This mode can be set up with special function to control Alarm min. and max. temperatures.
Additionally, it can be set up with so called Cable OK? function which uses channel digital
input (DI) with connected Current Monitoring Relay (CMR) to control availability of elec­tricity passing through a heating cable or similar.

PR mode or Power Regulation control

PR mode is time proportional power regulation with a simple duty cycle generator. Time

for status ‘Heating On’ during the chosen mode cycle can be set up by installer. PR control
typically can be used where one wants to dissipate a subjective amount of power.

This mode is also not connected to a temperature sensor and is therefore very suitable for
installation where it is impossible to install temperature sensor.
This control mode is similar to well-known DEVIreg™ 527 controller.

This mode can be set up with so called Cable OK? function which uses channel digital
input (DI) with connected Current Monitoring Relay (CMR) to control power consumption
or similar.

Manually On/Of mode

Manually On/Of mode (on the screen – MOn or MOf) is control with setting time period
during which relay status ‘Heating On’ or ‘Heating Of’ will operate.

NB: This mode can be used only on the base of 1S or PR modes and upon its completion controller
returns to the same mode from which it started.

4.4 Control modes, special functions, special statuses and settings

Each of 7 Channels has possibility to be individually set up with one of three control
modes – 1S (1 Sensor), PR (Power Regulation) and MOn/MOf (Manually On/Of).

The controller configurations for these 3 modes are the following:

1. Single sensor control with temperature sensor or 1S: one temperature sensor input,
one relay output;

2. Power regulation control or time proportional power regulation or PR: no sensor
input, one relay output;

3. Heating control Manually On and Manually Off with setting time period or MOn and
MOf: no sensor input, one relay output;

Together with any control mode could be set up or enabled/disabled some special functions
and statuses: “Relay status RO/RC”, “ CableOK?”, “ Relay test 5/30”, “ Channel ON/OFF” and
“Device ON/OFF”. Special functions and statuses are specified in chapters below.

Additionally, any Channel can be set up with status ‘not Active’ or Active = No. It means

Channel does not work at all and “empty” line appears on the Main Screen.

4.4.1 Active and Not Active Channel status

Not Active status can be used for applications there is no need to use full channel set of 7.
And view/line for the Channel which is not used is simply deleted from the screen.

By the way, standard factory setting for DEVIreg™ Multi supposes 1 active Channel #2.
The Main Screen with the only one Active Channel #2 is as on the picture below:

4.4.2 Relay status RO/RC – special setting for status ‘Heating On’

Heating On is a logical status for systems with temperature sensor. It means that real

sensor temperature is below set up level and controller should provide a special signal to
the system – either close or open relay contacts.

Heating On is a logical status that corresponds to heating system type. And some heating
systems, for example electrical, mostly need relay that closes contacts when the heating
is on. But another heating systems, for example water based, sometimes need relay that
opens contacts when the heating is on. For this purpose, DEVIreg™ Multi has possibility
to set up relay status for heating – ‘open’ or ‘close’.

Additionally, this relay status allows to implement both heating and cooling control, because
cooling is system having opposite algorithm to heating system.

The special setting for logical status Heating On is named Relay status RO/RC – Relay
Opened (RO) or Relay Closed (RC) each Channel Relay can be separately set up to status.

Factory setting – RC for relays or relays contacts which are normally opened (NO).

NB: This setting mostly works only when controller is powered!

Setting Relay status RO/RC can be done by the following menu sequence:
EN: Main Screen – Enter to Main Menu – Channels settings – Channel #X –

Relay status RO/RC – { Enter – Up/Down (RO/RC) – Enter }

EN: Main Screen – Enter to Main Menu – Channels settings – Channel #X – Relay

status RO/RC – { Enter – Up/Down (RO/RC) – Enter }

4.4.3 1S or Single Sensor mode and Sensor Type set up

4.4.3.1 1S mode

Single sensor control (1S) is mode with one temperature sensor.
And can be individually set up for any Channel.

The mode logic algorithm is the following: if sensor temperature is below set up value
then heating is turned on, and if sensor temperature is above set up value then heating is
turned off.

Some control parameters can be set up: mandatory – control temperature, optionally –
hysteresis and control alarm temperature diapason.

Temperature. 1S mode has temp. setting with max. diapason from -50°C degree to 200°C.
Default: 5°C.

NB: Each type of sensor has its own temperature range, which may differ from the maximum
given above.

Hysteresis.1S mode has hysteresis setting with diapason from 0,2 degree to 9 degree.
Default: 0,4°C.

NB: Hysteresis is used as the plus or minus value to the set temperature. For example, if
set temp. = 5°C and hysteresis = 0,4°C, then heating will turn off at the temperature of
5 + 0,4 = 5,4°C and accordingly turn on at the temperature of 5 – 0,4 = 4,6°C.

FEC | Produced by Danfoss ©18

Installation and User Guide DEVIreg™ Multi

Setting Temperature and Hysteresis can be done by the following menu sequence:

EN: Main Screen – Enter to Main Menu – Channels settings – Channel #X –

Temp & Hysteresis – #X Set temperature – { Down – #X Set +-Hysteresis }

EN: Main Screen – Enter to Main Menu – Channels settings – Channel #X – Temp &

Hysteresis – #X Set temperature – { Down – #X Set +-Hysteresis }

Temperatures Alarm. 1S mode has Temp Alarm settings with 3 parameters – alarm Enabled

or Disabled, alarm minimal temperature and alarm maximum temperature.
Alarm temperatures have unchangeable hysteresis 0,2°C.
Default – Temp Alarm is Disabled, Alarm min Temp = 0°C, Alarm max Temp = 60°C.

NB: It is the full responsibility of the installer/user to set correct alarm values that correspond
to the sensor type and for the specific application to avoid overheating of the cable, building
materials and so on.

Example of data for Temp Alarm settings and temperature Alarm Status is presented on
the screen below (lines 2-4):

Data on the picture above means the following: Temp Alarm is disabled for Channel #2 (Dis)
and Software does not control alarm temperature, alarm range set up with values from 0 °C to
60 °C, actual temperature of the sensor out of the range – Alarm Status = Yes.

Setting Alarm Temperatures and Alarm Enabling can be done by the following menu sequence:

4.4.4 PR or Power Regulation mode

Power regulation is time proportional power regulation mode with a simple duty cycle generator
with time set up during which heating is turned on within the period.

This mode can be individually set up for any Channel.

The PR logic algorithm is the following: if time counter is below set up cycle time when
heating should be on (On time) then heating is turned on, and if time counter is above set
up time then heating is turned off just up to the end of mode period.

Main screen with MOn mode data for one Channel is shown on the picture below (here
MOn started over 1S mode):

4.4.6 CableOK? – special channel function

CableOK? special function function can be used for checking the proper functioning

of the heating cable or other electrical equipment using a current flow control. In other
words, the current in the heater is controlled when the heating is turned on. Channel

Alarm appears as the result of state ‘not OK’ for this function (indication – symbol ‘!’ in
Channel line on the Main Screen).

For CableOK? function should be used additional device – for example Current Monitoring
Relay (CMR) or similar. CMR should be connected to the digital inputs DI1-DI7 corresponding
to Channel number. The main logic of CMR is the following – if current is not going through
device then 2 contacts/outputs are closed, and if current is going through device then 2
contacts/outputs are opened. This logic may also be in the opposite contacts’ state.

NB: This function works the only when Channel has state ‘Heating On’! In other words – if
heating is turned off (‘Heating Of’) cable or another heater does not consume any current and
accordingly there’s nothing to control.

This mode can be individually set up for any Channel. By default – function is Disabled for
all Channels.

For the state CableOK? = OK is used term Yes , and for the state CableOK? = not OK is
used term No respectively.

For CableOK? function can be set up two control parameters: Enable or Disable, and digital input
(DI) state for OK status – Normally Opened (NO) or Normally Closed (NC) on the COM DI input.

Enabled or Disabled. Function can be Enabled (En) or Disabled (Dis) for any Channel.
By default – Disabled.

CableOK? NO/NC. Setting for state of digital input (DI) when CableOK? function is OK. It
means if chosen NO for CableOK? = OK then digital input is not connected to the controller
input COM DI or there is an open circuit between DI and COM DI. And vice versa, if
chosen NC for CableOK? = OK then digital input connected to controller input COM DI or
there is a short circuit between DI and COM DI.
Default – NO or Normally Opened (this setting and proper CMR is shown on the picture above).

Settings CableOK? function can be done by the following menu sequence:

EN: Main Screen – Enter to Main Menu – Channels settings – Channel #X – Ca-

bleOK?– { Enter – #X CableOK? En/Dis – Down – #X CableOK? = NO/NC }

Data for CableOK? function is presented on =Channel data #X screen, for example as on
the screen below in 3 bottom lines:

Relevant data on the picture above means the following:

- CableOK? function is disabled for Channel #2 – ‘Dis’ on the screen, and software does
not control state of the input DI2;

- input DI2 has setting ‘NO’ (Normally Open) or, in other words, when current flows
through the cable/heater the input DI2 should not be closed on input COM DI;

- actual status for CableOK? function is OK or displayed ‘Ye s’ in the last line.

4.4.7 Channel ON/OFF – special function

Each Active Channel can be set up with status OFF or ON. OFF means that there is no
need to carry out Channel control algorithm due to, for example, a malfunction of the
cable or sensor, heating system installation and so on. In other words, Channel does not
perform algorithm and does not perform any Alarms. At the same time the Channel
saves all settings and for 1S mode active Channels show real sensors’ temperature and for
PR mode – shows real mode time. Additionally, it is possible to do/change any settings.

Settings Channel ON/OFF function can be done by the following menu sequence:

EN: Main Screen – Enter to Main Menu – Channels settings – Channel #X – Channel

ON/OFF – {Enter – #X Channel ON/OFF }

EN: Main Screen – Enter to Main Menu – Channels settings – Channel #X – Channel

ON/OFF – {Enter – #X Channel ON/OFF }

When Channel is OFF hash sign/symbol – ‘#’ – is presented on the 2nd position of Main
Screen line, for example:

4.4.8 Device ON/OFF – special function and switch

DEVIreg™ Multi controller can be set up by Menu with status OFF. This means that there

is no need to carry out any regulation for all 7 Channels. At the same time all Channels
save all settings and for 1S mode active Channels show real sensor temperature and for
PR mode – show real time. Additionally, it is possible to do/change any settings.

Settings Device ON/OFF function can be done by the following menu sequence:

EN: Main Screen – Enter to Main Menu – Device ON/OFF – {Enter – Turn device ON –

Down – Turn device OFF/ON }

EN: Main Screen – Enter to Main Menu – Device ON/OFF – {Enter – Turn device ON –

Down – Turn device OFF }
