INTRODUCTION
What is a Programmable Thermostat?
A programmable room thermostat is a device that combines the functions
of both a room thermostat and timed heating controller into a single unit.
The programmable thermostat is used to switch the heating system in
your home on and off as needed. It works by controlling the temperature
according to a series of programmed temperature settings that take effect
at different times of your choosing.
It's important to note that adjusting a room thermostat to a higher setting
will not make the room heat up more quickly. How quickly the room heats up
depends on the design of the heating system and heat-loss of the building.
The way to set and use your programmable room / floor sensing thermostat
is to find the lowest temperature settings that you are comfortable with
at the different times you have chosen and then leave it alone to do its
job. The best way to do this is to set a lower temperature first, for example
18°C, and then adjust the temperature gradually up or down by one degree
each day until you are comfortable with the temperature. The higher a
temperature setting required will result in more energy and fuel cost.

All types of thermostats need a free flow of air to sense the best
temperature, so they must not be placed in a cupboard or covered by
curtains or blocked by furniture. Radiant heat created by the sun, shining
directly onto the thermostat through a window and heat from nearby
electric fires, wall or lamps may prevent the thermostat from reading the
correct temperature in the room.
Our SnugStat Duo model allows for the use of one thermostat when the
situation normally requires two, for example – using this controller to use
both an underfloor heating system and a towel rail. The thermostat has
both a 13A and 5A relay, allowing for this multifunctional control of more
power consuming items.
