syncFURNACE OD Fan-coil:
syncFURNACE OD features an internal fan-coil, it is factory piped and wired, in some of our literature the
fan-coil is referred to as Zone 2. It provides warm-air heating, air circulation & 2 stage A/C (a/c coil &
condensor system sold separate) to the building via a HVAC duct system. The fan-coil system has been
optimized by Gradient to maximize efficiency and output leading heating capacity with lower supply water
temperatures. An optional outdoor sensor can be utilized to vary (reset) the heating coil supply water
temperature based on outdoor tempertarure, this further increases efficiency of the system and comfort
for home owners. The operating parameters are fully customizable via the settings screen in the
controller interface.
