Operating The Erv/Hrv With The Evolution Control

thermostat and follow same guidelines as installing a thermostat (locate approximately 5 ft (1.5m) above floor, mount on an inside partitioning wall, etc.)

Wiring

Remove top cover assembly from wall control and pass thermostat wire through hole located on back of control before attaching to wall. Connect Y, R, G, and B (yellow, red, green, and black) between wall control and ERV/HRV connector following color code. (See Fig. 5 and 10.) Replace top cover assembly.

NOTE: ERV/HRV wall control and circuit board operate on 12VDC.

Operation

The Standard and Latent wall controls have 4 basic modes of operation, OFF, LOW, HIGH, and INTERMITTENT. Be sure that all modes of operation are fully functional. See Table 1 indicating standard control operation.

1.With switch off, ERV/HRV is inoperative and the LED is out.

2.With switch on LOW, ERV/HRV continuously exchanges air with outside. If control is satisfied, blower will run in low speed, otherwise, blower will run on high speed. The LED is illuminated all the time.

3.With switch on INTERMITTENT, the ERV/HRV ex- changes air with outside on high-speed blower, and unit shuts down when control is satisfied. The ON LED is illu- minated all the time, and AIR EXCHANGE LED is illumi- nated only when unit is running.

Humidity Selector

The humidity selector is a built-in control designed to properly control the level of humidity in the house during the winter and summer months. This control helps avoid condensation problems in upper northern regions where indoor humidity is a problem during the winter season.

NOTE: This control is not to be confused with a dehumidistat used during the summer months to control high relative indoor humidity.

Table 2 recommends humidity levels to avoid condensation.

OneTouch Control

The OneTouch Control can be used as the primary wall control for the ERV/HRV. This control will step through the modes of operation with consecutive presses of the button. The LED indicates which mode is currently selected, Off, Intermittent, Low, or High.

NOTE: OneTouch Control does not have a humidity selector.

NOTE: OneTouch Intermittent mode exchanges air on low speed for 20 minutes per hour.

Latent Control

NOTE: For Latent Controls used with ERV;s, to ensure highest degree of humidity control in cooling season, the INTERMITTENT mode should be used.

Integrated Control

All units are equipped with an integrated control, located under the unit, in front of the electrical compartment. Use the push button (1) to control the unit. The LED (2) will then shows on which mode the unit is in. Integrated Control overrides Wall Control function. When LED is off, ventilator responds to Wall Control command. See Fig. 11.

If a problem occurs during the unit operation, its integrated control LED (2) will blink. The color of the blinking light depends on the type of error detected. Refer to Troubleshooting for further details.

NOTE: The ERV/HRV may be controlled using the Evolution system control. The ERV/HRV may be connected using either a NIM or a 4-Zone Damper Module. See the appropriate instructions if using the NIM or a 4-Zone Damper Module for connection instructions.

The Evolution system control will simultaneously control the ERV/HRV and the indoor blower.

Push Button Timers may be used and are connected to the ERV/HRV. However, the Evolution system should be set to continuous fan to ensure that the fresh air is circulated in the home. In a Zoned System, at least one zone should be set to continuous fan.
