Installation Instructions - Smart temp ISIS User Manual

Smart Temp
The ISIS from Smart Temp Australia P/L is a multistage auto
change-over programmable thermostat. It offers industry
leading features, an impressive warranty and is extremely
simple to use and set up. By taking the time to follow these
instructions the ISIS will perform faultlessly and provide the
end user with many years of trouble free service.
Use this installer instruction sheet for mounting and setting up the
ISIS, and the User manual for information on programming and
setting the real time clock etc.
Mounting the ISIS or Optional Remote Sensor.
The ISIS can only be as accurate as the temperature sensor permits.
It is therefore essential that the ISIS (or remote sensor(s)) are
installed in a location that is typical of the ambient room temperature.
Do not install the ISIS in a draft, near a floor/wall/roof register.
Consideration also needs to be given to drafts that may be present
near external opening doors, chillers or windows. Where possible
mount the ISIS or temperature sensor out of direct sunlight and on
internal walls.
Further, when mounting the ISIS be aware of drafts that may travel
down the inside of walls, (especially if mounted on external walls). It
is important to fully block all cable entry holes to prevent any of these
drafts effecting the internally mounted ISIS temperature sensor.
It is recommended to mount the ISIS or remote sensors between
1.5 & 1.8 metres from the floor where possible.
Cabling
Normal "AC style" low voltage cabling can be used for the ISIS control
wiring. Where long cable runs are likely for the remote temperature
sensor and/or remote override switch it is recommended that
screened cable be used, especially where this cable is run close to
high voltage electrical wiring.
Do not used twisted DATA cable (CAT 5).
Wiring
Refer to the wiring diagrams on the reverse of this sheet to connect
the ISIS to the equipment. Please note, the ISIS is both a Heat Pump
& Heat Cool thermostat. The mode of operation is selected with
clearly marked jumpers. It is important that you have the jumpers in
the correct position for the type of AC equipment installed.
Programming & Set Up
DO NOT INSTALL THE LITHIUM BACK UP BATTERY UNTIL
AFTER THE REAL TIME CLOCK HAS BEEN SET.
After first connecting the AC power to the ISIS it is important to wait
15 ~ 20 seconds before attempting to press any buttons, this gives
the ISIS time to "BOOT UP" and run its internal diagnostics routine.
The ISIS will FAIL this initial BOOT sequence if the lithium battery is
installed at this point. If the battery has been mistakenly installed at
this point, remove the battery, power the ISIS down and wait 2~3
minutes before re applying power to the ISIS.
Use the programming instructions supplied in the user manual to set
the realtime clock and program the ISIS to the end user requirements.
After the ISIS has been set up and programmed insert the lithium
battery into the battery holder on the base of the main PCB.
Turn of the power to the ISIS wait 10 seconds and re connect the
power to confirm that the ISIS retains memory and the backup
battery and electronics functions correctly.
With the ISIS in Auto Change Over mode, test all thermostat modes
by both raising the set temperature above the ambient temperature
and verifying correct heater operation. Next lower the set
temperature to below the ambient temperature and verify the
correct operation of the cooling equipment.

Installation Instructions

A dvanced Installer Functions
The ISIS has two concealed menus that are used to either fully lock
the thermostat (or restrict the temperature control range) or to adjust
the advanced installer functions. Each menu uses its own security
code. It is important that these security codes are only given to
authorised persons as these codes are fixed in ePROM and cannot
be changed. If these codes are compromised then unauthorised
persons will be able to make changes that will effect the
performance or efficiency of the AC system.
Locking & Unlocking the ISIS
Press the ALARM / RESET button. The ISIS will display "
Using the Set - button adjust this to read "
RESET to enter the Lock menu. Pressing the ALARM / RESET
button again will lock the ISIS.
Repeat this procedure to unlock the ISIS.
Setting Advanced Functions.
Press the ALARM / RESET button. The ISIS will display "C50".
Using the Set + button adjust this to read "C55". Press the ALARM /
RESET again to enter the Setup menu.
The ISIS will display "HL XX" This is the highest value you wish the
user to be able to adjust the set temperature to. This value can be
adjusted using the Set + or SET - buttons. Default value is 31
Press the ALARM / RESET button again to display "LL XX" This is
the lowest value you wish the user to be able to adjust the set
temperature to. This value can be adjusted using the Set + or
SET - buttons. Default value is 16
Press the ALARM / RESET button again to display "HA XX" This is
the value you wish the ISIS to activate the over temperature alarm.
This value can be adjusted using the Set + or SET - buttons.
Default value is 45
Press the ALARM / RESET button again to display "LA XX" This is
the value you wish the ISIS to activate the under temperature alarm.
This value can be adjusted using the Set + or SET - buttons.
Default value is 04
Press the ALARM / RESET button again to display "Db XX" This
permits adjustment of the dead band value, which is the value in
deg C between heat and cool modes that you wish the ISIS to
remain idle. This value can be adjusted using the Set + or SET -
buttons. Default value is 1 deg C.
Press the ALARM / RESET button again to display "Ot XX" This
activates the ISIS optimised start function "Ot 00" is optimised start
off. "Ot 01"is optimised start on. This value can be adjusted using
the Set + or SET - buttons. Default value is "OO" (off). Optimised
start will Start the ISIS before the programmed start time to ensure
the area is at the desired temperature by the programmed start time.
Press the ALARM / RESET button again to display "AH XX" This
sets the ISIS After Hours run on time period. This value can be
adjusted to values between "0" and "4" hours using the Set +
or SET - buttons.
Default value is "02"
Press the ALARM / RESET button again to display " t 00"
This permits you to adjust the temperature calibration of the
thermostats temperature sensor. This value can be adjusted to
o
o
values between "-6 c" and "+6 c" using the Set + or SET - buttons.
Default value is "00" (Calibration Offset is nil)
Press the ALARM / RESET button again to return the ISIS to normal
mode.
