3.0The Programmers

3.1Getting Started

1.Ensure that both gas and electricity are turned on to the appliance.

2.The Gas Safe registered installer will have set-up the appliance to a programme of your choice and it should be providing heat and hot water in line with your requirements. These can be altered via the wall-mounted room unit or the programmer on the product fascia, both of which are shown in this section. Section 4.0 and 5.0 detail how the timings and settings for your heating and hot water can be changed.

3.2Programmable Operator Unit (POU)

1.This is located at the base of the appliance on the front cover. It displays important information about how the appliance is working and allows you to alter settings to configure the operation to your requirements.

2.It can be removed from the appliance to act as a programmable room unit (PRU) when mounted in a wall cradle accessory. This then becomes a temperature sensor and programmer.

3.If your Ecogen appliance has been installed using the existing room temperature and time controls the installer should have made sure that the appliance programs for the central heating and domestic hot water are set to 24hr operation – see sections 7.1 and 7.3 - choose ‘On’ in both cases.

4.Refer to the instructions for the existing programmers for setting the timed periods and the room temperatures. The programmable operating unit will display the boiler flow temperature and any errors see section 9 onwards.

3.3POU as a Programmable Room Unit (PRU)

1.The Room Unit Wall Cradle accessory is available in two formats.

a)Hard Wired i.e fixed to a wall, the screen illuminates upon operation.

b)Radio Frequency, cradle mounted and portable, with no permanent screen illumination.

2.The Radio Frequency unit is powered by three AA batteries located in the rear of the unit behind a slide down panel. If battery power is depleted a warning symbols appears on the display screen, replace the batteries.

3.The operation of both Radio Frequency and hard wired units is identical.
