Summer Fan; Program Mode; Temperature Setting; Programming The Switching Times - Thomas & Betts ENERGYMIZOR 2 Gebrauchsanleitung

Providing the installed heaters are equipped with a summer fan facility, the Energymizor can enable the fan
to give ventilation in summer months.
• Pressing the FAN key displays the following screen.
• At this point you must press ENTER or if you wish to abort this operation press the DELETE key.
!
If the FAN key does not operate, the fan output is being used to give constant or automatic summer fan
control. This is described later in this manual.
From the Normal (RUN) mode screen, pressing the PROG
button will display the following screen.
Before you can access the Energymizor you must enter the passcode of the user. This passcode is set to
0000 as a factory default but may be changed at any time by the user to ensure security. This process is
explained under section 4 (code).
1) Temp
This section is used to changed the temperature settings.
• You are now prompted to enter the required temperature for the
DAY periods (EG:22). This must be entered as two digits.
• When complete, press Enter
• You are now able to select whether you require night temperature.
Selecting ON enables you to set a NIGHT setback temperature.
• Press Enter when you have set the required night
temperature.
If S.Fan (see System Setup/Fan Control Setup) has been enabled, you are prompted to enter the summer fan
temperature. The summer fan temperature is calculated by a differential
setting. For example a differential of 03 means that the summer fan
temperature will be 03°C above the day setting. Therefore there is no risk
of the DAY temperature being higher than the Summer Fan setting.
2) Data
The DATA section is where you are able to set the daily switching periods. There are 3 switching periods per
day available.
• Press PROG and enter the security code of the user
• Now select 2 to enter the DATA menu
You can see on screen now that we are prompted to enter the switching
period 1 for Monday. So using 24 hour clock notation, enter the required
start time. (EG: 08.00)
Now press enter to accept the Start time and to move the cursor to the end time setting.
We are able to program the required End time, for example 17.00. Don't forget to use 24 hour clock notation.
When complete, press Enter to accept the programmed switching time and to move onto period 2 Monday.
