Poly-Tex Poly-Vent (Retrofit) - Manual (Page 20)

Thermostats for the Poly-Vent system should be mounted approximately centered between each sidewall and centered from
front to rear of the structure. They should be mounted at eye level. However, some growers prefer to mount thermostats at
bench height.
Initial start-up: PVII Two Stage Poly-Vent
When inflating the Poly-Vent for the first time - before wiring the thermostat - turn on the blower. Moving from one end to the
other, manually help the Poly-Vent tubes up so that they do not twist.
The included wiring diagrams should be used to wire the thermostat into the system. Note that the wiring circuits more resemble
a "heating" circuit than a "cooling" circuit. This is the correct way to wire your thermostat. Please wire exactly as shown for
correct results.
With the Poly-Vent deflated, slowly turn the thermostat to a higher temperature until the blower is activated. If the system is
operating properly, the blower will activate and inflate the PVII system.
After the Poly-Vent has been successfully inflated, check for proper complete inflate/deflate cycle operation.
Now adjust the thermostat to the desired temperature to be maintained in your structure.
NOTE: If you have a BUBS (Back-Up Blower System) the BUBS is not generally wired to the thermostat so that if it is activated,
the Poly-Vent will remain inflated and will not cycle again until the power is restored.
NOTE: THIS BASIC POLY-VENT OPERATION PAGE IS FOR PVII (SINGLE-STAGE) SYSTEMS ONLY.
