2. INSTALLATION
The MTH100 DI must be installed on a 35 mm DIN rail and in watertight enclosure.
Installation should comply with current local standards.
Any installation or work of any nature should be carried out by a certified professional.
The equipment must feature a ground-fault breaker.
The installation must be properly grounded.
The power supply should be switched off prior to any work being carried out on the equipment
(including cleaning).
Initial START-UP : HEATER OPERATING TEST.
Programme the control module (minimum 1 step),or start it up in “MAXI” PRESET MODE
(see page 18) after adjusting setpoint Tc to a value greater than the ambient temperature
(see page 9).

3.3 PROGRAMMING PROCEDURE
Before programming your control module, consult the example below and fill in the
programming grid (see page 8).
This example is not programmed in the module.
By default, the 3 setpoints Tc, Tr and Tn are set at "00°C", the 7 steps of the 7 days of the week are set
at "00:00=Clr" and all the dates are set at "00 Jan 01" (1st January 2000).
 ADJUST SETPOINTS (MENU A)
To make optimum use of your heating, there are 3 available temperature setpoints :
Tc : Comfort temperature (ex : working day in the factory).
Tr : Reduced temperature (ex : preheating half an hour before worker's arrival).
Tn : Night temperature (ex : to prevent freezing outside factory working hours).
See programming grid on page 8.
 WEEKDAY PROGRAMMING (MENUS B AND C)
Specify a typical timetable for each day of the week (Monday to Sunday)
- Before 07.00 : factory closed (Tn setpoint maintained since the day before).
- 07.00 - 07.30 : preheating half an hour before worker s ' arrival (setpoint Tr).
- 07.30 - 12.00 and 13.00 - 17.15 : working day (setpoint Tc).
- 12.00 - 13.00 : lunch break (setpoint Tr).
- After 17.15 : factory closed (setpoint Tn until new programming step)
Example of programming for Monday
Setpoint Tr Tc Tr Tc Tn
Step 1 2 3 4 5
Time 07.00 07.30 12.00 13.00 17.15
Tn Tr Tc Tr Tc Tn
Step programming is only required with a SETPOINT CHANGE.
Example : programming is not required on Monday at 00.00 since the heating is already set to Tn
(as from Friday 11.30).
See programming grid on page 8.

9
 EXCEPTIONAL DATES (MENU D)
10 exceptional dates are available to pre-programme your heating on dates where timetable differs from
the one set for the corresponding day : public holidays, inventory days, make-up days, etc...
Assign one of the following programmes to each of these dates : Sunday (normal non-working day),
Monday (normal working day), E1 or E2 (see exceptional programmes on page 15)
Example : Christmas day (Tuesday 25 december)
Although Christmas Day is on a Tuesday, it is a public holiday and therefore
heating is programmed as for Sundays (Tn temperature).
NOTE : - adjust your exceptional dates as and when required.
- fixed-date holidays (e.g. Christmas) are programmed once and for always.
- variable-date holidays (e.g. Easter Monday) must be re-programmed every
year.
See programming grid on page 8.
 EXCEPTIONAL PERIOD (MENU E)
The same principle applies as with exceptional dates : one exceptional period is available for special
programming over a several day period.
Example : Holidays (from 04 to 10 February)
To programme as a Sunday (Tn temperature).
NOTE : adjust your exceptional period as and when required.
See programming grid on page 8.
NOTE : The programming of an exceptional period overrides the programming of an
exceptional date or normal days when these are included in the exceptional
period.
 EXCEPTIONAL PROGRAMMES (MENU F)
There are two exceptional programmes E1 and E2 available (in addition to normal Sundays and
Mondays).
Each of these two programmes has 7 steps.
These two programmes are for attributing to an exceptional date or period.
Example : Friday 4 january
Make-up day for 24 december. Clock out at 16.00 instead of 11.30.
See programming grid on page 8. (programme E1)
