BoilerMate Heating/Hot Water Controls
The current BoilerMate A-Class SP Sol incorporates separate heating/hot water and
solar control systems.
The BoilerMate A-Class SP Sol heating and hot water controls operate in the same way
as the basic BoilerMate appliances but the single channel clock and the two rocker
switches have been replaced by a two channel digital clock. (Channel 1 controls the
gas boiler /hot water and Channel 2 the heating.) Details of how to set the clock are
shown in the user instructions which are provided in the plastic wallet fixed at the
bottom of the front panel. Recommendations regarding the setting of Channel 1 are
provided on the label adjacent to the front panel controls (see below). Channel 2
should be set as normal to control the heating on/off times required.
Label 1 - Channel 1 of this digital clock is dedicated to heating of the hot water. This
can be set to hold off the boiler during periods of potential high solar gain periods
eg 10.00 am to 16.00 pm allowing maximum solar contribution to the thermal store.
Central heating channel 2 will not be affected by holding off the boiler and operates
independently of channel 1.
If a high hot water demand is expected or the appliance runs out of hot water due to
poor solar gains, the setting of Channel 1 can be overridden which will bring on the
boiler and ensure hot water is made available. Dependant on use/weather, the 'off'
times suggested above can be adjusted as necessary to ensure adequate amounts
of hot water are available.
The Switch 6kW electrical emergency back up system is fitted to this appliance. This
is switched on by moving the 'mode' rocker switch from normal to switch and is used
in the event of boiler failure. It is unlikely to be needed in Summer but can be used
in Winter as required to provide some heating and hot water in conjunction with the
solar input until the problem can be resolved.
It is an emergency only system and must not be used if the main system is
working correctly.
