providing CHILLED water to the suite manifolds.
On a call for COOLING
•

The thermostat will signal the manifold 24vac zone valve to open.
•
ADer a 3 minute delay (Hme delay to allow Chilled Water to reach the Unit):
•
The Fan LED will come ON
•
The Thermostat will then modulate fan according to demand, from "Low Speed " to "High Speed"
When the Building Central System is providing Chilled water and the suite has a call for HeaHng, the zone valve
remains closed and the Thermostat
does not
turn the fan on. All LED’s stay off.
