Smart Temp
Operation
Great effort has gone into making the Smart Temp electronic
thermostat an extremely simple thermostat to program and use.
By reading and understanding these simple instruction, you will
realise and use many of the features this thermostat has to offer.
Programming and set up of this product has been designed as a
very methodical procedure. The same buttons (and sequence of
buttons) are used to program and set up this product.
Setting The Clock
As the 42-157 thermostat is a programable thermostat, when you first
place the batteries into the thermostat, (or after you have pressed the
reset button) you must set the real time clock. This is essential as the 42-
157 thermostat uses this clock to turn on the heating and cooling at the
times that you request.
Setting the clock is a simple procedure that only requires a few key
presses. When the batteries are first installed, the LCD will indicate the
current room temperature and 12AM on the Clock as
shown in Fig1.
In this example, lets set the clock for 2:16PM on
Saturday.

Programming the Thermostat.
The 42-157 is a "5+2" day programmable thermostat; 1 program group is
for the 5 weekdays, 1 program group is for the weekend, hence the 5+2.
Further to this, the 42-157 has 4 programs per day. What this means is
that up to 4 times each day the thermostat will change the temperature of
the home.
As an example, in heating mode - just before you get out of bed in the
morning you may want the home to heat to 20 Deg
you are at work you may not want the house to get any colder than 15
Deg
. Just before you arrive home at the end of the day you
(Program 2)
may wish the home to be at 21 deg
night you may want the home to be kept at a cosy 17 Deg
Programming this thermostat is no more difficult than setting the clock. In
programming mode however the thermostat will cycle between Hours,
Minutes and Temperature for Program 1. By continuing to press the
program button it will continue to cycle through Hours, Minutes and
Temperature for Program 2. Then Hours Minutes and Temperature for
Program 3 etc.
Again, after 20 to 30 seconds of NOT pressing a button the thermostat
will return to normal mode.

Tip.
If you only require 2 or 3 programs per day, simply set the unrequired programs to
the same value as a used program. For example, should you only require 2
programs for the weekend (wake at 7:00am at 20 deg and Sleep at 11:00pm at
17Deg. Simply set program 1, 2 & 3 for 7:00 am at 20Deg and program 4 for
11:00pm at 17Deg. This way, at 7:00 the thermostat will move straight to program 3,
and stay in program 3 until 11:00 pm (program 4 start time)
