Congratulations on the purchase of your new Electronic Thermostat!
Your new Smart Temp thermostat
design philosophy. As a result, if properly installed your new electronic
programmable thermostat will provide you with years of trouble free and
reliable service.
The Smart Temp 44-400 has been designed to be attractive, highly reliable and
simple to use. Please take the time to read these simple instruction to familiarise
yourself with the function and features offered in this product.

Programming the Thermostat.
The 44-400 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 44-400 has 4 programs per day. What this means is
that up to 4 times each day the thermostat will automatically 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
(
Program 1
)
. While
you are at work you may not want
your home to get any colder than 15
Deg
(
Program 2
)
. Just before you arrive home at the end of the day you
may wish the home to be at 21 deg
(
Program 3
)
, and while you sleep at
night you may want the home to be kept at a cosy 17 Deg
(
Program 4
)
.
Programming this thermostat to follow your customised profile is no more
difficult than setting the clock. By tapping the program button the
thermostat will step between Hours, Minutes and Temperature for
Program 1. By continuing to tap 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.
Step 1
Use the switch to select either heating mode or cooling mode.
(Please note: This thermostat is capable of controlling both a Heating & Cooling system, The use of this
thermostat does not indicate that your home or office has a Heating AND Cooling system installed)

Step 2
Press the button. Program “1” indicator as well as the Weekdays
will be displayed. The “HOURS” and AM or PM on the
LCD will flash. (See fig 5) Press the or button to
adjust the hour to the time you wish the first program to
start.
Step 3
Press the button again. Now the minutes will flash
for program “1”. Press the or button to adjust the minutes to the
time you wish the first program to start.
Step 4
Press the button again. Now the Temperature for program “1” will
flash. Again, by pressing the or buttons you can adjust the desired
temperature you require for program “1”
Pressing the program button again simply repeats the above procedure
for Programs 2, 3 & 4 for the weekdays, then the 4 weekend programs
(indicated by “Sat” & “Sun” in the LCD).
Tip.
If you only require 2 or 3 programs per day, simply set the un-required 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)
To adjust the Cooling program. Repeat the above procedure with the
switch in the “Cool” position.
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.
As the 44-400 thermostat is a programable thermostat, when you first
place the batteries into the thermostat, (or after you have reset the
thermostat) you must set the clock. This is essential as the 44-400
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.
Step 1
Press the button, the display will illuminate, the
temperature indication will go blank and the hours digits
will flash as in fig 2.
Step 2
By pressing the or buttons, adjust the hours to
read 2PM.
Step 3
Press the button again. Now the minutes flash.
Pressing the or will permit you to adjust the
minutes to “16”.(Fig 3)
Step 4
Press the button again. Now the day will flash as in fig 4.
Press the or to adjust the day to read “Sat”.
Step 5
Press the button again to return to normal mode. Alternatively by
NOT pressing a button for 20 to 30 seconds the thermostat will
automatically go back into normal mode. The clock is now set.
In this example, Pressing the button cycles through Hours, Minutes
and Day. (Indicated by the flashing digit). By pressing the or button
permits you to make adjustments to the flashing digit. This same
principal is used through out the programming of this thermostat.

Installation Instructions
These instructions assume the
thermostat has
knowledge of Heating & Air conditioning systems, the terminology
used in these systems and of the HVAC industry requirements.
It is an offence in Australia for unqualified persons to make any changes
to Airconditioning systems. Failure to observe this may void equipment and
thermostat warranty, property insurance and cause irreparable damage to the
thermostat or equipment connected to it.
installer of this
Remove the wall plate from the rear of the
thermostat by pressing the release tabs on the
top and bottom of the thermostat ands swinging
the base away. (Fig 10)
Position the wall plate on the wall and pull the
wires through the large opening. Mount the
wall plate with the supplied wall anchors or
other suitable means, ensure the thermostat
base is level to add to the appearance of the installation.
Referring to the supplied wiring diagrams, connect the system wires to the
appropriate terminals on the thermostat base plate. Ensure the screws are
tightened securely to prevent potential problems caused by loose
connections. Push excessive wire length back into the wall cavity.
If the opening in the wall is large there may be a potential for a draft to blow
through the wall cavity and onto the temperature sensor on the back of the
thermostat. To ensure correct thermostat operation it is important to block
this hole. Failure to do so may cause inaccurate or erratic system
performance.
On the back of the 44-400 thermostat there are three clearly marked
selector switches. These switches are used to select the temperature
display format, deg C or deg F, the type of system the thermostat is
controlling (heat pump or heat with add on cool), recovery mode and
whether the fan is called by the thermostat HE (Heating Electric) or by the
system HG (Heating Gas) .These switch locations are shown in Fig 11.
Adjust these switches to their correct position to suit the type of system
controlled.
If you change any of these switch
positions AFTER you have
installed the batteries, you MUST
press reset for the new switch
settings to take effect.
Snap the two halves of the
thermostat back together taking
particular care to align the
thermostat pins with the clips on the base plate of the thermostat and that
the temperature sensing bead will not become crushed between the two
case halves.
Test all thermostat modes by both raising the set temperature above the
ambient temperature in heat mode and verifying correct heater operation.
Next lower the set temperature to below the ambient temperature with the
thermostat in Cool mode and verify the correct operation of the cooling
equipment.
Please Note: The Smart Temp 44-400 thermostat is a low voltage
thermostat only. Do NOT directly switch 240VAC equipment or damage will
result. Should it be necessary to switch 240VAC equipment the optional
Smart Pak 03N will be required. See fig 12 below.
The Smart Temp 44-400 is a battery powered thermostat and does NOT
require the use of a neutral. If this thermostat is replacing an existing A/C
equipment powered thermostat, disregard the neutral wire.
Failure to heed this warning WILL result in thermostat damage.
