Override Test
To use override test function, a thermistor must be connected to the
control board. Unit must not be in defrost mode during an override
test.
HIGH SPEED
1. Disconnect ERV/HRV from 115vac.
1. Unplug wall control wires at control module terminal block
inside ERV/HRV.
2. Plug ERV/HRV back to 115vac.
3. Attach a wire across J3--8 and J3--9 (B and G) on control
module terminal block.
4. Push in door switch, thiswill initiate a high--speed exchange.
LOW SPEED
1. Unplug ERV/HRV from 115vac.
2. Disconnect wall control wires at control module terminal
block inside ERV/HRV.
3. Plug ERV/HRV back to 115vac.
4. Connect a 3.0 K ohm resistor between B and G on control
module terminal block.
5. Push in door switch, this will initiate a low--speed exchange.

4. Blower Speed Selection
Three--speed blowers are factory connected to electronic control
board on HIGH-- and LOW-- speed taps of blowers. Installer can
easily change low--speed tap to medium--speed tap so electronic
control will select between high and medium speed. Connections
can be changed at motor location (See Table 6 and 7).
To change low speed to medium speed, proceed as follows:
1. Unplug unit from 115vac.
2. Locate blower assembly.
3. Locate red wire anb lue wire coming from blower assembly .
4. Unplug red wire from quick connect.
5. Unplug protecting cap quick connection from blue wire and
put on red wire coming from blower. The cap is a safety
insulator.
6. Connect red wire of main harness to blue wire.
7. Replace wires.
