Volt-free setback switching of the unit’s 
controller PCB using single-pole 
latching switch and / or volt-free 
normally open relay contacts.

To avoid the unit being inadvertently  
left in Setback Mode, it is recom-
mended that only one latching switch 
is fitted. 

Volt-free setback switch or

normally open relay contacts
