Smart Temp 44-400 User Manual
Installation Instructions
Smart Temp
Note:
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.
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 has been designed to be attractive, highly reliable and
simple to use. Please take the time to read these simple instruction to familiarise
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 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
DAY/TIME
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.
DAY/TIME
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.
DAY/TIME
Press the or to adjust the day to read “Sat”.
Step 5
Press the button again to return to normal mode. Alternatively by
DAY/TIME
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
DAY/TIME
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.

design philosophy. As a result, if properly installed your new electronic
programmable thermostat will provide you with years of trouble free and
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
fig 2
fig 3
fig 4
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.

Functions
The Smart Temp 44-400 has three override modes. These are
very useful should you wish to make changes to the set
temperature without completely reprogramming the thermostat.
The three override modes are described below.
Temporary Override
In this mode, the override temperature change will only last until
the NEXT program starts, hence it being called a “temporary
override.” For example, you might use this type of override when
you want the home to be a little warmer (or cooler) to
accommodate a dinner guest. Adjusting the evening program
(program 3) will only last until the sleep program (program 4)
begins later that night, or until it is manually canceled as
described below.
To make a Temporary Temperature Override.
Press and hold the or button to change the LCD display to
indicate the “SET” or desired temperature. After approximately 1
second, the display will blink once to indicate the temperature can
now be adjusted. Press and hold the or button to adjust the
set temperature to your new desired value. You will note that the
Program indicator in the LCD now flashes to indicate that a
temporary temperature override is now active.
Permanent Override.
The Smart Temp 44-400 permits the permanent override of all
temperatures and programs with a simple button press. This may
be useful when you go on holidays and not wish to let the home
cool below at 12 deg C, 24 hours per day, 7 days per week.
Another common use of the permanent override is for those that
may not wish to use the Smart Temp 44-400 thermostat as a
programable thermostat, and use it in a “manual thermostat
mode”, In this way you can select a desired permanent
temperature and by using the switch turn the thermostat
off or on manually as desired.
To make a permanent Temperature Override.
Should you wish to set a permanent temperature and override all
program and clock functions first select heating or cooling mode
using the switch. Next, using the or buttons select
the desired temperature. To lock this temperature permanently
simply press the button once. The thermostat will indicate
HEAT OFF COOL
HOLD/RET
“HOLD” in the LCD confirming the permanently hold function is
active. It is then a simple matter to turn the thermostat off and on
at the held temperature using the switch.

To set a Holiday period Temperature Override.
Should it be desirable, you can set a permanent temperature
override that will automatically cancel itself in a given number of
days. For example, you may be going on holiday for 14 days and
would like the home to be warm or cool to greet you when you
return.
To set the Holiday override first select either heating or cooling
mode with the switch. Next, using the or button set
your desired temperature. Now, press the button twice to set
HEAT OFF COOL
the “holiday override mode”.
The LCD will look like the example shown in fig 6.
Tapping the button the LCD will increase
Day / time
the counter to show the number of days until
the holiday override expires and normal thermostat operation
begins. If you set too many days, pressing the button will
permit you to reduce the day counter.
To cancel an active Override
When you no longer require a temperature override and wish to
resume normal thermostat operation simply tap the button
until the LCD no longer shows the word “Hold”. The 44-400 will
now alter the homes temperature automatically according to your
programmed schedule.
12 or 24 Hour Clock
The 44-400 thermostat is able to display the time in the
conventional 12 hour “AM / PM” or the 24 Hour time format. To
change the time format press the button then the
button to toggle the time format.
Low Battery Warning
Your Smart Temp 44-400 is fitted with a two stage low battery
warning. When the batteries are first detected to be weak the first
stage Low battery warning will be indicated by the low battery
symbol in the LCD. (See fig 7a). It is important
to replace the batteries with Alkaline “AA”
batteries when this symbol is flashing. When the
batteries become too weak to maintain normal
thermostat operation the thermostat enters the
second stage low battery warning (fig 7b) which
shuts the thermostat down.
During a battery replacement process you have
approximately 2 to 5 minutes once the batteries are removed to
place fresh alkaline batteries in the thermostat before program
data is lost.
Please note: the back light function is suspended
when the low battery indicator is on.
Auto Recovery Mode
Your 44-400 thermostat has the ability to use advanced energy
management techniques if activated by your installer.
Auto Recovery mode will calculate the most energy efficient time to
control your heating or cooling system to ensure your ideal
programmed comfort temperature is reached by your programmed
start time.
When your thermostat is in recovery mode the LCD
will alternate between the word “RECO” and the
current time, See fig 8.

Notes on recovery mode
Recovery mode is enabled / disabled by a switch marked

“recovery” on the inside of the thermostat. This is normally set by
the installer.
nRecovery mode will not operate if the LCD shows the word
“HOLD”
nThe Recovery function can be cancelled by pressing the
HOLD/RET
button. The recovery mode will then be transferred to the next
scheduled event.
Filter Change Indicator
To ensure your heating and cooling system is operating at peak
performance, your 44-400 thermostat monitors the total time your
heating & cooling system has been running. When 400 hours of run
time has elapsed the word “FILT” will be alternatively displayed with
the clock on the LCD to remind you to clean or replace your return
air filter (if fitted) see fig 9a.
To review the total filter time
Press the button to review the total filter time.
In the example shown the filter has been used for
232 hours and 19 minutes. Fig 9b.
To reset the counter and cancel the filter warning

for 5 seconds to reset the counter to 000 .
Backlighting.
The 44-400 is fitted with an electro-luminescent back light. When
any key is pressed the back light will turn on and remain on for 8
seconds after the last button has been pressed. If ambient noise
level is very low you may hear a high pitch noise when the back light
is on. This is normal and is there is no cause for concern.
When the thermostat battery is low, the back light function is
suspended. Replace the batteries with 2 “AA” alkaline only.
Span Setting
For the best compromise of energy management and comfort your
44-400 will control your heating and cooling to within 1 deg C of
your set temperature in both heating and cooling modes (Span 2).
In all but the most unusual circumstances you should find this
setting is adequate. Should it be required, you can change this
factory default value to widen or tighten the control
tolerance by pressing both the and together
and choosing an alternate setting. (Fig 10)
Span 1 will maintain your room temperature very close to your set
Fig 10
temperature by turning your heating or cooling system on and off at
relatively short intervals. This is the least energy efficient setting.
Span 2 - factory default setting.
Span 3 will permit your room temperature to vary slightly from your
set temperature by delaying the start of your heating or cooling
system and running it longer. This is the most energy efficient
setting.
Note: When your thermostat is re-set, the factory default value
of Span 2 will be restored.
