Tamper Proof Controls
Selection switch and temperature can be fixed in one position to prevent adjustment. The temperature control may alternatively be restricted to a max/min range.

Central Control
Central controllers are available in two formats, Pilot Wire and Mains Borne Signalling. Pilot Wire is ideal for new-build installations where a signal cable is installed with the power cable at first fix stage.

Pilot Wire (ET range only)
Pilot wire installations require a control wire from the programmer linking each heater. Up to 15 heaters per zone can be connected to one controller.

Pilot wire installations are ideal for new-build applications where the control wire can be installed with the first fix wiring. No additional receivers are required, making this a cost effective central control option.

Mains Borne Signalling (ET range only)
Mains Borne Signalling (MBS)
MBS is ideal for refurbishment projects where cabling is already installed. The VA MC controller is heater mounted and requires a receiver, VA MI on each additional heater to be controlled. Up to fifteen heaters can be linked to one VA MC controller.
