Fantech RTS5 Installation And Owner's Manual
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 fit 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.
