• UV Window interlock : This parameter allows for the selection of the window closed switch to be
interlocked with the UV light option. When the window interlock is on, the window must be closed for
the UV light to operate. When the window interlock is off the UV light can be turned on regardless of
window position.
NOTE : In addition to the TOUCHLINK system UV window interlock there is a double redundant UV window
interlock relay. To override the UV window interlock for service purposes only, both interlocks must be changed
through the
TOUCHLINK
system and shorting the relay connection (see electrical schematic for reference).
• Blower Window Interlock : This parameter allows for the selection of the window closed switch to be
interlocked to the blower. When the blower interlock is on, the blower will turn off when the window is
closed. When the blower is off, the blower will continue to run when the window is closed
