Installation and Operating Instructions
ES-LCD User Control
3.3 Timed Programmes
There are two custom programmes available (custom
program A & custom program B) for each control.
If it is more energy efficient, use one program for summer
operation and the other for winter operation to prevent
unnecessary heating or cooling.
Within each program; up to 32 timed periods can be set up.
Please note that each timed period must not span more than
one day; e.g. start on Monday and stopping on Tuesday is
not allowed.
Please note the program only stores the periods when
the fan is on. The fan is assumed to be off at all other
times that have not been defined.
This is the display screen of a default blank program.
Note that a valid start and end time is not present.
Any program period with
÷
in either start or end time will
be ignored.
Set Prog:
The top line is showing the program and timed
period being edited; in this case Program A and timed period 1.
Highlight this and use the ‘<’ & ‘>’ adjustment keys to move
to other program/periods.
Start time:
valid start time must be in the range 00:00
to 23:59.
End time:
valid end time must be in the range 00:00 to
23:59 and must be greater than start time.
Day:
define the day(s) associated with this period; options
are Mon to Sun, weekdays (Mon to Fri inclusive) weekends
(Sat & Sun) or ALL (i.e. everyday).
Speed:
define the fan speed associated with this period;
options are 1 to 10 inclusive, manual, auto or trickle. If ‘auto’
speed is selected, the fan will use an Ecosmart sensor to
govern its speed which in some cases will result in the fan
being switched off. Please refer to appropriate installation
guide for the sensor. If ‘trickle’ is selected, the fan will be
locked in lowest speed until another Ecosmart enabler is
activated; e.g. ES-PIR.
When this happens, the fan will run at the maximum speed.
‘Manual’ will use the last speed setting as starting point.
Function:
this selects the operating function of the unit.
The default is ventilation only unless an appropriate heating
and/or cooling option is selected in the initial system set up
(see 3.2).
ES-TEMP Thermostat Option:
Normally the ES-TEMP is used
as a fan speed control, but not this option.
Here the temperature measurement of the ES-TEMP is used
by the LCD to decide whether to bring on the ventilation,
heating or cooling depending on the temperature measured at
the ES-TEMP location. The measurement range is limited to
the set-point of the ES-TEMP plus/minus 10 degrees; e.g. a
set-point of 22
o
C will give a measurement range of 12
o
C to
32
o
C. Therefore we recommend the target temperature of the
ES-TEMP is set to 20-25
o
C for most applications.
Only one ES-TEMP should be fitted if it is used in this way.
Do not program the fan speed to ‘Auto’ when using this
feature as it could produce an unexpected result.
The available options are none, ventilation, heating, cooling,
venti heating and venti cooling. This option
is disabled if none is selected. For example, if ventilation and
heating is selected for a period, the thermostat can be
selected to switch on the heating function when the room
temperature had fallen before a set point.
Temperature operating range:
this sets the upper and/or
lower temperature limit of the thermostat option if the option
is selected. For example; selecting heating if temperature is
below 18
o
C.
When you are happy with the program period,
press ‘Save’ to confirm the settings before moving on to
the next period.
The example above shows the fan will run at speed 1 between
midnight and 8am every Monday. The heating will be selected
if the ambient temperature at the ES-TEMP is below 18
o
C.
The example above shows the fan will run at speed 7
between 8:01am and 6pm every Monday to Friday.
The heating will be selected if the ambient temperature
at the ES-TEMP is below 18
o
C.
