Operating Modes
The thermostat has three separate operating modes being :
AUTOmatic, MANual and TIMER ECONO.
NOTE: Only one mode can be active at a time.
AUTO
The Automatic mode maintains the room temperature
according to the user programs.
Press the AUTO button. The “PROG” icon and the running
program will be displayed.
Momentarily pressing the up or down button displays the
temperature set point of the running program.
MAN
The Manual mode allows the user to bypass the
programming and operate the thermostat as a simple non
programmable thermostat.
Pressing the MAN button displays a hand symbol indicating
Manual mode is active.
The set temperature can be adjusted by pressing the
Temperature Up or Temperature Down button in 0.5 C
increments.
TIMER ECONO
When going on vacation or leaving the home for extended
periods (up to 7 days) the Microstat provides a useful
TIMER ECONO function.
This function provides a means to hold the homes
temperature to a temporary fixed temperature for up to 7
days. At the end of the TIMER ECONO mode the Microstat
will automatically return to Auto mode as described above.
This operating mode allows the user to temporarily override
the program to maintain a lower heating temperature
(during vacations etc) thereby providing savings in energy
costs.
To activate the Timer Econo mode :
1 Press and hold MAN button for three (3) seconds.
2 The clock symbol, the return time and the ECONO
temperature set point will be displayed.
3 Press DAY, HOUR and MIN keys to specify the return time.

heating system has been running. This value is then displayed
so that you may clean the filter if installed.

has been ON and after 250 hours of system operation, the
