Manual for 7-Day Programmable Thermostat (395KB)

Ideal for:
• Radiant or convection electrical heating system
• Circulator control in a hot water system
• Electrical hot air furnace
• Hot air, gas or fuel conventional furnace
• Air-conditioning system
Not recommended for:
• Gas or fuel furnace or boiler with wall chimney, if they include a combustion gas
purging cycle exceeding 30 seconds. To verify this point, check the duration of
the delay between the heating command sent by the thermostat and the moment
when the burner actually goes on.
• Multi-zone systems, where several thermostats command a single heating or
air-conditioning unit.
In the last two cases, the conventional mode is recommended.
Regulation Cycles
In proportional adaptive mode, the TH141 adapts the regulation cycles to your sys-
tem capacity. When cycles are very short, the temperature variation in the room is
very low and the comfort level very high. However, very short cycles can generate
premature wear of your system.
It is therefore important to adjust the cycles to your type of installation.
In general, the bigger your heating or air-conditioning unit is, the longer the cycles
should be. The TH141 offers the possibility of programming regulation periods of 5,
10, 15 or 20 minutes using switches 1 and 2 at the back of the unit.
We recommend the following options:
• 5 minute cycle Not recommended for central units
• 10 minute cycle for Radiant or convection electric heating
• 15 minute cycle for Central heating and
air-conditioning unit
• 20 minute cycle for Commercial unit

2.Conventional mode with anticipation
If you want the conventional mode with anticipation, push #5 switch down.
This mode commands the system's On and Off cycles when the temperature read
by the thermostat reaches pre-set levels. This mode is compatible with all heating
or air
-conditioning systems.
P
rogrammable Span
When the thermostat is in conventional mode with anticipation, it is possible to pro
-
gram a span, that is temperature variations between ON and OFF orders of your
system. These variations are programmable between 0.3 and 0.6 °C (0.5 and 1.1 °F)
and they correspond to the following positions of switches #1 and #2:
We recommend the following options:
* 240 volt heating with relay (baseboard, convector, radiant ceiling, etc.)
d) Heating Fan Control
This function determines whether the heating system fan is opera-
ted by the thermostat or by the plenum's temperature of the heating
unit. In general, the fan is operated by the heating unit. However, if
the fan does not turn on and the thermostat requires heating for
more than one minute, push #6 switch up.
