IHC conversion calculator

Count the panel once and get the parts list that replaces it.

Updated: September 2026

What it does

Count the inputs, outputs and dimmer channels in the existing IHC panel. The calculator turns them into a complete parts list with EAN numbers, ready to order.

It reflects our recommendations — a starting point, not a specification. The tool itself is in Danish.

Betjening og funktioner

Energimåling kræver PM-relæer forsynet med 230V.
Vælg Nej, hvis al betjening sker med batteritryk – så medregnes der hverken overdragsrelæer eller inputmoduler.
Vi anbefaler at benytte relæernes og lysdæmpernes indgange – lidt mere fortrådning, men mindre programmering.

Antal enheder

Udgange til lys og andre belastninger, der skal tændes/slukkes.
Kanaler der skal kunne dæmpes (erstatter IHC Dimmer).
Hele trådløse tryk med 4 knapper (erstatning for IHC Wireless).

Reading the result

The list reflects what we would fit. Other combinations work, and a panel with an unusual constraint — width, an existing supply worth keeping, a circuit that must survive a network outage — will justify departing from it.

Check panel width before ordering. The cheapest parts list per output is not always the one that fits. This is the constraint that most often forces a rethink, and it is the one the calculator cannot see.

Save or print it with the quote. Gem / print som PDF gives you the parts list on A4 with the date, the quantities and the notes — and nothing else from this page. In six months that sheet is the only record of what the count was, and the next electrician in that panel will be working from it.

The link carries the answers. Kopiér link til beregningen puts the counts in the address, so a colleague opens the same result rather than a blank form.
