Troubleshooting

Part 4 — Operate and fix.


30.1 Start here

Nine times out of ten it is one of these:

#
Check
Where

1

Yellow dots on a floor plan

Design tab

2

Addresses do not match the hardware

Device manager

3

The project was never uploaded

[☰]Save to central unit

4

The CU is running a different project

"Projects are the same."

5

The wire points the wrong way

Wire manager — actor and consumer

6

The wire has no function on it

Wire managerFunctions:

7

A condition never passes

Wire functionConditions

8

The function is the wrong type

Digital on a dimmer, or the reverse

9

The fault is electrical, not in the project

Monitor — is the output switching?

Check 9 settles most arguments. If Monitor shows the relay switching and the light stays off, your project is right and the wiring is not.


30.2 Connection problems

State or message
Meaning
Do this

Disconnected

No connection

Check IP, cabling, power

BadPassword"Please try it again."

Wrong CU password

Get the right one

UpdateRequired"Please update CU firmware."

CU firmware too old

Error

Connection failed

Read the information console

Ping test fails

It is a network problem

Fix the network before anything else

Run Ping test first, always. It separates a network fault from a software fault in one click.


30.3 Compile errors

When iDM3 cannot turn your project into something the CU can run, the Compile error button on the Project ribbon tab lights up. Nothing is uploaded.

Click it and read the error. Common causes: a device removed but still referenced, a function whose type no longer matches its consumer, a condition pointing at something deleted, an exceeded limit.


30.4 CU error codes

[☰]CU configurationCU setting shows Error code:, with Title:, Body:, ExtendedInfo: and Code:.

Reset error clears it — but read it first. A code that returns immediately is telling you something.

The full code list is in Advance/Languages/CUErrors.*.lang, and Rev19 chapter 18 has a state-code overview.


30.5 Project and device messages

Message
Meaning

"Projects are NOT the same!"

The CU is running something different

"Projects tree is [x], system tree is [y]."

Which parts differ

"Unable to delete this object because is i use!"

Something still references it

"Not remapped devices detected"

Devices left unmapped after conversion

"Please remap device or change/remove its links"

Use ReMap unit

"Module type [0x…] is not supported."

Not available in this version

"Max count of modules type"

A module limit reached

"The item can not be inserted here!"

Wrong place in the device tree

"Unable to add item"

Usually a group type mismatch

"Error when loading file."

The project file may be damaged

"Unable to find selected disk location!"

Use Save as and choose a new path


30.6 iDM3 itself

Symptom
Try

Will not start

Confirm .NET Framework 4.8

Starts then closes

Read Exception.excp and IDM.log

Opens with a project error

New, then reopen your project

Wrong language

SettingsLocalizationSelect language

A recent project will not open

"File '…' could not be opened. Do you want to remove this item from Recent list?" — the file moved or is damaged

Very slow on a large project

Turn off both animations in SettingsVisual effects

Log files

In the install folder:

File
Contents

IDM.log

General application log

comunication.log

Communication with the CU (spelled that way)

monitoring.log

Monitoring activity

monitorData.log

Monitored data

Exception.excp

The last unhandled exception

Attach these when contacting support. They usually contain the answer.


30.7 Behaviour that looks wrong but is not

Symptom
Explanation

Pressing the button again does nothing

Digital switch ON is not toggle — use DIGITAL_SWITCH

The impulse does not restart on a second press

Digital_Impulse_ON ignores an output already on — use a timer

The light runs to 100 % after dimming

Missing ANALOG_STOP_LEVEL_CHANGE on Long up

A 10-second ramp takes 2 seconds

Ramp length is the 0→100 % time; partial changes are proportional

A group refuses a device

Wrong group type — relays and dimmers cannot share a group

The dimmer forgets its level

Analog switch value only moves between 0 % and 100 %

A program cannot be saved

No day or month ticked in Periodical settings

Sunset switching is an hour out

The CU's Time zone

Holiday mode lost after a power cut

non volatile not ticked on the system bit

SMS never arrives

The GSM: plug is red, not green

An incoming SMS does nothing lasting

It gives a one-second pulse — latch it into a system bit

A function block does nothing

Its inputs and outputs are not plugged in, or Connect was not pressed

A macro did not apply

Its Type does not match the actor type

Editing a macro changed nothing

Macros are copied into wires, not linked


30.8 Heating

Symptom
Check

Nothing heats

Monitor → Heat/Cool areas — is Required-Heat-AOUT demanding?

Required temperature is wrong

The time plan, and which plan the area uses

Heating and cooling fight

Check the difference between temperature of heating and coolingOn

One room never heats

Its Heating output; the shared Heating supply

No room heats

The Heating supply relay

It heats then stops

Maximal temperature; the window detector

It runs all night

The schedule; look for a stuck manual override

Monitor → Heat/Cool areas is the tool for all of these. Comparing Actual-Therm-AOUT with Required-Therm-AOUT tells you immediately whether the problem is the schedule or the plumbing.
