MagIQtouch – Builder Lock Activated (Controller Locked / Unable to Adjust Settings)


⚠️ Safety Notice – MagIQtouch Controllers and Components / Accessories

MagIQtouch controllers and accessories control devices used to operate and monitor compatible evaporative coolers, ducted gas heaters and add-on cooling systems.


Installation, commissioning, servicing, fault finding and repairs must only be carried out by suitably qualified and licensed personnel where applicable. Before commencing work, complete a task-specific risk assessment and ensure electrical safety procedures, safe access and appropriate PPE have been considered. All work must comply with applicable regulations, standards and manufacturer requirements. 


Particular care must be taken when working on or around electrical systems, communication wiring, control circuits, roof spaces, ceiling spaces and associated heating or cooling equipment connected to the controller. 


Do not proceed if safe access, electrical isolation requirements, required clearances or appropriate safety controls cannot be achieved and maintained. This controller forms part of a complete heating and/or cooling system, and incorrect installation, testing or servicing may result in equipment damage or unsafe operation. 


Safety takes priority over diagnosis, repairs, installation schedules and customer expectations. If the task cannot be completed safely, it must not proceed until the risks have been adequately controlled.


Overview

Builder Lock is a configurable access restriction within the MagIQtouch controller. It operates similarly to a password and must be intentionally set via the controller interface.

In most cases where Builder Lock is active and the code is unknown; this is typically due to:

  • Unintentional user input (for example, navigating service menus and entering codes such as 7378), or
  • External interruption (such as a power loss occurring while settings are being accessed)

This behaviour is consistent with normal system operation and is not indicative of a product fault.

Important

  • Builder Lock is a unique user-set code
  • There is no override or master reset code available
  • If the code cannot be identified, access cannot be restored via the controller

Applies To

  • MagIQtouch controllers used with heating products only

    • (e.g. ducted gas heaters using MagIQtouch)

  • Controller revisions:

    • 44R0719 and earlier

Note:
Later revisions (44R0920 and above) include improvements that reduce the likelihood of unintended activation.

Common Trigger Scenarios

  • Entering 7378 (service access code) and navigating beyond the intended menu
  • Advancing through prompts without recognising the Builder Lock screen
  • Multiple or repeated button presses
  • Power interruption while accessing menus or settings

Symptoms

  • Lock icon displayed on screen
  • Settings cannot be changed
  • Customer unsure how lock was activated

Recovery Procedure

1. Access Builder Lock Screen

  • Navigate to:
    • Settings → Heater → Builder Lock / Unlock

2. Enter Service Access

  • Enter 7378
  • Press CONT

3. Attempt Default Entry

  • Leave code as:
    000000
  • Press CONT twice

4. Confirm Response

  • Screen should display:
    • “INCORRECT CODE”
  • This confirms the controller is responding to input

5. Power Cycle Controller

  • Isolate power to the wall control
  • Restore power and allow system to reboot

6. If Still Locked

  • Attempt access using any known or likely codes the customer may have entered (i.e. 737800, 007378)

7. Repeat if Required

  • Reattempt steps if needed
  • Button presses may not always register on first entry

If Lock Cannot Be Cleared

If the Builder Lock code cannot be identified or the above steps are unsuccessful:

  • The system cannot be unlocked via software or service code
  • The only available resolution is to:

    → Replace the ICS (Integrated Control System) (heater PCBA as it is locked)

Technician Notes

  • Builder Lock is a deliberate function, not automatically applied by the system
  • No factory override is available by design
  • This applies only to heating systems using MagIQtouch
  • Resolution depends on:
    • Correct code entry, or
    • ICS replacement where the code is unknown

Recommended Customer Guidance

  • Do not enter service menus unless instructed
  • Avoid entering codes unless their purpose is known
  • Treat Builder Lock as a secure access feature
