INSTALLATION AND OWNER`S MANUAL

RST-5 - 20/40/60 MINUTE TIMER

OVERVIEW

The RTS5 is a low voltage remote timer switch that can be used with a compatible HRV / ERV to

activate its highest ventilation rate for 20, 40 or 60 minute.

It is designed to t in a single-gang box and comes with screws to mount the RTS5 to it and a

Decora® plate.

COMPATIBILITY

The RTS5 is compatible with the Fantech Flex series and the Fantech VHR150R.

INSTALLATION

Selecting the correct wire

We suggest you use a 2-wire, 18 gauge insulated copper wire to connect the RTS5 to the HRV / ERV. We sug-

gest that the wire have a clear indication to differentiate the two wires in order to facilitate maintaining the polar-

ity of the wires during wiring.

Installing the wire

This wire should not be installed so that it runs along high voltage wires in order to avoid electro-magnetic inter-

ference.

Up to 5 RTS5 can be installed in parallel. Ideal locations are bathrooms, the kitchen and the laundry room.

We suggest installing a steel single-gang electrical box to facilitate installation.

Wiring the control

Ensure that the HRV / ERV is unplugged before continuing to avoid damaging it.

1. Insert the stripped end of the wire into the + and – of the terminal block

on the back of the RTS5.

2. Secure in place with a pen-type screwdriver.

3. Note the wire’s polarity, i.e. which wire is connected to + and -.

4. Remove the 6-position, green terminal connector inside the HRV / ERV

by gently pulling it out.

5. Pass the other end of the wire through the bushing located on the top of

the HRV/ ERV and push the wire down into the cabinet so it reaches the

terminal connector position.

6. Insert the stripped end of the wire into the T+ and T- positions of the

terminal connector. Secure with a pen-type screwdriver.

*Ensure you maintain polarity; T+ is connected to + position on the RTS5 terminal

block.

7. Re-connect the terminal connection in the HRV / ERV.

  If the light turns off when you press the Fantech Timer button a second or third time, make sure your HRV/ERV model is listed in the compatibility section of this manual. Also, ensure that you press the button a second or third time less than 1 second after the initial press.
