iCommand-Touch
The built-in 4-machine sequencing makes this one of the cheapest ways to sequence a small room — set it up before quoting a separate master controller.

Sensor pin resistance & signal values
Pin-level resistance and signal values for the sensor types this controller uses. Works offline. De-energise the panel and lift one lead before ohming any element.
Wiring notes
- Touchscreen is a separate HMI from the I/O board — a dead screen with a running unit usually means the HMI ribbon or 24 V HMI supply, not the control board
- USB firmware updates must use FAT32 sticks under 32 GB
- Sequencing between machines uses the RS-485 terminals marked MB-A/MB-B
Known issues & field notes
- Resistive touch calibration drifts in hot cabinets — recalibrate from the hidden corner-touch service routine
- Units with early iConnect modems lose cloud connection after carrier 3G sunsets — upgrade to the LTE module
Service menu PIN set by distributor at commissioning.
