MOUNTING

The Powersaver Dual Flexi should be removed from the mounting box by unscrewing the 2
captive pattress screws.

Conduit box mounting - Use either holes marked ‘C’ to secure to a single gang box or the two
holes marked ‘B’ for a double gang box. Cable entry is through the rear breakout.

Surface mounting - Use the two holes marked ‘A’. Cable entry is through the most appropriate cut
out.

Remove the appropriate cable entry cut outs before xing the box, where possible drill the box to
provide a close tting entry for cables, taking care to remove sharp edges.

Ensure outgoing cables to the immersion heaters are securely clamped in the box. All surface

wiring adjacent to the box should also be clamped appropriately or trunking used.

WIRING

Use a three core heat resistant cable with a minimum
conductor size of 1.5mm connection to a 3kW heater.
Connect the incoming wires to the terminal block as
follows:

1. Live In

2. Neutral In

3. Heater Neutral

4. Boost Load

5. O Peak Load

Link terminals 4 & 5 if using a single immersion heater.

Immersion Water Heater Controller

User Instructions

WHAT IS THE POWERSAVER DUAL FLEXI?

The Powersaver Dual Flexi is a water heater controller that combines ease of use

with the efcient control of your water tank during off peak rate electricity periods
to provide hot water when required.

This product differs from a simple time switch as it has programs built in that match
with Economy 7, Economy 10 and Eco 20:20 electricity tariffs. This ensures your
tank operates during off peak times avoiding expensive peak use.

As such this controller is not freely programmable, you can minimise the program
times within your off peak period but not go outwith it,

You may need to contact your electricity supplier to conrm which tariff you are
on and your specic off peak times before the product can be installed.

Should more hot water be required then pressing the ‘BOOST’ button will switch on

the boost immersion element for ½, 1 or 2 hours to heat up part of the tank.

Where extra hot water will be required every day at the same time a Boost program
of up to 2 hours can be entered. Again this will operate the boost immersion element
to heat up part of the tank.

ON/OFF SWITCH

In the OFF position the electrical supply
to the water tank immersion heater is
disconnected even though the display

continues to operate. In the TIMED
position all programs and functions are
active.

BACKLIT DISPLAY

The display is temporarily backlit for 15
seconds when mains power is supplied
or if any button is pressed. This is
useful where a product is installed in

cupboards or dark environments.
