Thank you for purchasing the Smart Temp
ERT
(
Electronic Room
Thermostat). This thermostat is the product of years of research into
the requirements of the Australian consumer. It has been designed
and manufactured to the highest quality standards and designed to be
a highly reliable, simple to use and a feature rich thermostat.
To take full advantage of the features and functions of this thermostat
please find time to read and understand these simple operating
instructions.
All user functions are easily accessed by pressing the 6 clearly
marked soft touch buttons found on the face of the thermostat. The
thermostat is also fitted with a Liquid Crystal Display that indicates
room temperature, set temperature as well as the thermostat
operating mode.
To Select the Required Operation Mode
The ERT is capable of fully automatically controlling the room comfort, or permitting manual override of
many of the thermostat functions depending on the preferences of the occupant. For example, the ERT has
the ability to have the fan running continuously when the thermostat is on, regardless of the requirement for
heating or cooling. Or the ERT will only bring on the fan on when there is a requirement to heat or cool the
building (Auto Fan Mode as indicated by “A.Fan” on the LCD). Further, the ERT will allow the selection of
heat only, cool only or auto changeover mode where the thermostat will automatically switch between
heating and cooling mode depending on ambient and set temperature (indicated by “Heat” & “Cool”
displayed simultaneously on the LCD).
By pressing the Mode button the thermostat will toggle through seven (7) operational modes. These
modes are
1 - Cool with continuous fan operation.
2 - Cool with Auto Fan operation.
3 - Heat with continuous fan operation.
4 - Heat with Auto Fan operation.
5 - Heat / Cool
(Auto change over mode)
with continuous fan operation.
6 - Heat / Cool
(Auto change over mode)
with Auto fan operation.
7 - Continuos Fan only operation. (No heating or cooling required)
To Turn the Thermostat On or Off
Pressing the On/Off button on the face of the thermostat toggles the thermostat
between the On and Off mode. The current operation mode is indicated in the top
left of the LCD by an arrow pointing to the word “ON”. When the arrow is Dark
(visible) the thermostat is in the ON mode and controlling the heating or cooling equipment connected to it.
When the arrow is not visible the thermostat is OFF and not controlling the room temperature.
To Select the Fan Speed
The Smart Temp ERT is capable of controlling heating and cooling equipment fitted with up to three fan
speeds. By pressing the Speed button on the LCD, the thermostat will switch between Low, Medium, High
and AutoFan Speed mode. As each press of the Speed button is detected, the current fan speed will be
indicated on the LCD by the appropriate arrow being On (darkened). Auto Fan Speed mode will be
indicated when all three fan speed indicators are On in the LCD.
When Auto Fan Speed mode is selected, the thermostat will increase or decrease the fan speed of the
heating or cooling equipment depending how far away the Set (or desired) temperature is from the current
room temperature.
In Auto Fan Speed Mode, as all fan speed indicators are on, the current automatically selected fan speed
is indicated by the flashing arrow.
