READ AND SAVE THESE INSTRUCTIONS
NOTE: If the control is to be installed in an electric box, do
not perform steps 3 and 4.
If ducts have to go through an unconditioned space (e.g.: attic), always use insulated ducts to prevent condensation
formation inside and outside ducts, which could cause material damage and/or mold growth. Moreover, if fresh air
to building duct and/or stale air from building duct goes/go through an unconditioned space, the unit must be set
to operate continuously in cold conditions (below 10°C/50°F). Continuous air movement inside ducts will prevent
condensation formation. The unit can be stopped temporarily for maintenance and/or repair purposes in such
conditions. (Refer to section 2.2 from unit User and Installer Manual for more details.)
