(25) Do not short circuit the 24 V AC supply (pins 35 & 36) against any pin designated as
ground (GND) as this may damage the low voltage circuitry. The system is protected by a
manual re-settable 2-Amp thermal fuse located on the left hand side of the remote connector.
Ensure that there is sufficient resistance in any external circuit to prevent this value being
exceeded.
(26) The remote is fully isolated, there will be a small AC potential difference above the
chassis ground/earth. It is important to understand that switching can only be achieved
against the ground of the remote interface as opposed to the earth of the unit.
(27) The onboard computer protects the system from misuse therefore it may not always be
possible to make the system functional. You may need to wait a short time before engaging a
different mode.
