7-DAY OPTIMISER
The SVT is a fuel-saving controller which can replace a conventional
time switch on a heating system and provides a variable start time
dependent on the fall of room temperature during the off period.
It is used to switch on and off central heating systems and will
substantially reduce fuel consumption compared with fixed time
starting. In all but the very coldest weather the start time is delayed until
the latest time consistent with the amount of heat necessary to regain
the required temperature at occupancy time. In very mild weather this
delay can be as much as five hours later than in cold weather and fuel
savings of between 10% and 25% are possible.
By relating the start time to the inside temperature rather than the
outside temperature, the insulation and thermal mass of the building
are taken into account.
The SVT makes the benefits of optimum start control available for
small buildings because the capital outlay for the installation is low and
no skilled personnel are needed to operate it.
