DESCRIPTION
The
•It will provide the required ventilation by delivering fresh air to meet I.A.Q. (Indoor Air Quality) requirements through CRV portion of the device.
•It will provide up to 525 CFM of free outdoor cooling CFM when the outdoor ambient temperature is below the outdoor thermostat setpoint.
Operating the
Ventilation is accomplished with (2) blower/motor assemblies for maximum ventilation at low sound levels. The intake and exhaust blowers are programmed independently and are balanced to maintain a slight positive pressurization in accordance to ASHRAE 62.1 Standard.
The Ventilation Package is also provided with filters to reduce the required service needed and to further improve the I.A.Q. The exhaust air blowers are protected by disposable filters, and the intake air blowers are protected by washable filters. Both are accessible without the need for tools.
CONTROL WIRING
Refer to Low Voltage Connection (Figure 19).
Reference Figure 23 for Control Sequence of Operation.
Open disconnect to shut all power OFF before doing this! Failure to do so could result in injury or death due to electrical shock.
SETTING THE VENTILATION CFM LEVELS
The
Perform the following steps:
1.Open front swinging doors of main unit (by popping front door latches).
2.Throw main power disconnect to the “OFF” position to eliminate risk of injury or death due to electrical shock.
3.Remove six (6) screws holding front CRV door in place (see Figure 22).
4.For CRV blower speed, locate “Brown Wire with White Trace” that has as black terminal on the end where it connects to the terminal strip (see Figure 24).
5.Move the “Brown Wire with White Trace” to the corresponding CFM level needed in accordance with Figure 24.
6.For Economizer Blower Speed, locate “Pink Wire” that has a black terminal on the end where it connects to the terminal strip (see Figure 24).
7.Move the “Pink” to the corresponding CFM level needed in accordance with Figure 24.
