American Standard ERVR200A9P00A Percent Timer Control Pt, For use with all ERV models, Operation

User’s Information

PERCENT TIMER CONTROL (PT)

The Percent Timer Control automatically energizes and de- energizes the energy recovery ventilator every hour, ensuring ventilation for the home around-the-clock. The PT control has two status lights (See Figure 2). One is the power light located in the upper left hand corner of the control. The other light will be one of the Runtime % lights. The power light is on whenever the PT control is calling for the ERV to run. The Runtime % light is located along the right side of the control. The Runtime % light indicates the amount of time per hour the ERV will operate. Set the control per your local code or ASHRAE Std 62.2 and your ventilator will run once every hour.

FOR CONSTANT OPERATION: Press the fan icon until the 100% light is on. The “Runtime %” light turns on. The ERV unit will run continuously.

FOR MINIMUM VENTILATION REQUIREMENT OPERATION: Set the control at the percentage that meets local code or ASHRAE 62.2. Press the fan icon until the light for the percent desired is on.

TO TURN THE ERV OFF: Press the fan icon until all lights are off. The control is off. The ERV motor is de-energized. (Power is still persent inside the unit. Always unplug cord from outlet before servicing!)

GENERAL SETTINGS: For systems installed in an area with high humidity. The Percent Timer should be set to deliver the Minimum Ventilation Requirements.

VACATION SETTINGS: For systems installed in an area with high humidity. If the A/C system thermostat setting is elevated or set up while on vacation or for extended periods of time (over 2 days), the Percent Timer and ERV should be turned OFF. After returning from vacation or when the system thermostat is lowered to normal daily setting, the Percent Timer and ERV should be reset to the previous runtime %.

WHEN WINDOWS ARE OPEN: When windows are open in your home the Percent Timer and ERV should be turned OFF.

NOTE for ERV systems with more than one control:

Another control may be causing your ventilator to run -even if the runtime % light on this control is off. If you wish to keep your ventilator from running, check that none of your controls are calling for unit operation.

Installation

1.Install control in a standard 2" x 4" electrical box, with a minimum depth of 1.5", with the two screws provided.

2.Wire Size: 18 gauge, no more than 500 feet. Wiring is non-polar.

3.The two wires from the ERV should be attached to the ‘C’ and ‘R’ positions on the terminal block on the back of the PT Control. See Figure 13.

4.Use Lutron Decora™ cover plate to complete the installa- tion (supplied by installer).

PUSH BUTTON POINT-OF-USE CONTROL (OPTIONAL ACCESSORY)

For use with all ERV models

Operation

The Push Button (PB) Point-of-use Control lets you manually turn on your energy recovery ventilator for a short period of operation – for example, when you are using a bathroom. The PB Control must be connected to a PT control to operate.

20-40-60 minute ventilation control:

Press the fan icon and your ventilator will run for 20 minutes (See Figure 3). Press again and the unit will run 40 minutes. A third press provides for 60 minutes of operation. Percent Timer Control does not need to be on for the PB Control to operate the ERV unit.

You can cancel a cycle at anytime. Just press the fan icon and hold for about five seconds.

You can start another cycle by pressing the fan icon.

NOTE for ERV systems with more than one control:

Another control other than the push button may be causing your ventilator to run. If you wish to keep your ventilator from running, check that none of your controls are calling for unit operation.

Installation

4.Install control in a standard 2" x 4" electrical box, with a minimum depth of 1.5", with the two screws provided.

5.Wire Size: 18 gauge, no more than 500 feet. Wiring is non-polar.

6.Two wires from the PB Control should be attached to the ‘PB” positions on the terminal block on the back of the Percent Timer Control.

7.For two PB controls, one wire from each can be twisted together and inserted into a single position on the terminal block on the Percent Timer Control. The wires must be a 18 gage solid wire. If more than two PB controls are attached or 18 gage stranded wire is used then pigtails must be inserted into the ‘PB’ positions on the Percent Timer Control and the leads attached to the pigtails with wire nuts.

8.Use Lutron Decora™ cover plate to complete installation.
