Heatrae Sadia Electromax Installation Guide - Advanced Water

a sealed (pressurized) primary system. It
is suitable for conventional radiator based
sealed system functional and safety controls,
including the circulating pump and primary
expansion vessel. The boiler automatically
responds to lower central heating loads by
reducing (modulating) the boiler output which
saves wasteful on-off cycling. For summer
use the boiler can be switched off on the
Electromax control panel, however a “pump
exercise” facility will energise the circulating
pump for a brief period every day to prevent
pump seizure through long periods without
use.
Time and temperature control of the central
heating is by means of a Programmable
Room Thermostat which is supplied loose
with the Electromax for remote siting in a
suitable, convenient position.
The necessary cold water mains supply
controls are supplied in a kit for installation
on site in a suitable, convenient position.
