3.1 Getting 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.
3.2 Programmable 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.
3.3 POU 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.
