Advice to Users

Promax Store provides domestic hot water from a

high performance, high efficiency version of a

traditional storage cylinder. Whenever hot water is

used it is replaced by fresh cold water and, provided

this occurs when the programmer is in a ‘DHW ON’

period, the boiler will operate to raise it to the

temperature you have selected. This will take from a

few minutes to around 20 minutes, depending on how

much hot water has been drawn from the storage

cylinder. Please adjust the time and temperature

settings on the programmer according to your

experience of the boiler’s performance and your

household’s need for hot water.

3.0 Repressurising System

bar

3.1 Central Heating System Pressure

1. The normal operating water pressure is

between 1 and 2.5 bar (Fig. 1). If the pressure

exceeds 3 bar the safety pressure valve will

operate and a fault is indicated. Contact your

installer.

2. It may be necessary to repressurise the system

occasionally (Fig. 2). A filling device (the filling

loop) is fitted on the boiler itself.

3. The filling loop consists of two taps and a

separate metal braided hose pipe.

4. Only when repressurising should the hose be

connected between the two taps. No tools are

necessary for this, but ensure that the wing nuts

on the hose pipe ends are tightened onto the

taps.

5. Fully open one of the taps first, and then while

watching the pressure gauge, carefully open the

second tap.

6. When the needle on the gauge is indicating 1

or more, turn both taps off.

7. Disconnect the hose from the taps (a small

amount of water may be present) and remove it.

Keep the hose in a safe place for future use.

7.1 Introduction

1. The built-in programmer is an electronic 7-day

central heating and hot water control, designed to be

easy to use and understand. Properly programmed it

will help you save energy and create a comfortable

environment in your home.

2. For convenience, morning and evening ON/OFF

periods have been pre-set in the programmer ‘memory’

and will be retained, even if the mains power supply is

interrupted. Details of these ON/OFF periods are given

in the next section, together with step-by-step setting

instructions.

features :

* Up to 3 On-Off time periods every 24 hours plus

the option of programming different times for each

day of the week.

* A central heating ADVANCE button allowing an

instant switch from OFF to ON or ON to OFF

without affecting normal settings.

* A hot water BOOST button giving an extra one hour

period.

7.2 Buttons, Indicators & Symbols

Most of the control buttons on the programmer are dual

purpose. They can be used as SET buttons for inputting

time of day. ON/OFF times, etc, or as SELECT buttons

for using the advance facility and choosing override

programme options.

will automatically return to normal RUN mode and

any changes made since the last press of the

ENTER button will not be saved.

i) Press the SET button so that the SET INDICATOR is

pointing to the CLOCK position on the front of the

programmer. the DAY OF THE WEEK INDICATOR will

now flash (see Fig. 9).
