The TH140 control algorithm includes an anticipation function which reduces the discrepancy between the thermostat reading and the temperature at the center of the room.</div> <div> .<FONT SIZE="3" COLOR="#000000" FACE="Arial" > </FONT></div> <div> <B>2) </B><B><U>PROPORTIONAL TH101/102/104/106/108</U></B></div> <div> This regulation is based on the latest temperature reading, which occurs every 15 seconds. In fact, the controller decides which percentage of power to send to the electric baseboard depending on the temperature requested by the user and the temperature measured by the thermostat. Thus the thermostat reacts very quickly, ensuring optimal comfort. The screens display the percentage of power sent as follows: </div> <div> .<FONT SIZE="3" COLOR="#000000" FACE="Arial" > </FONT>.<FONT SIZE="3" COLOR="#000000" FACE="Arial" > <IMG SRC="09e534d0.gif" border=0 width="83" height="77" ALIGN="BOTTOM" HSPACE="0" VSPACE="0"></FONT></div> <div> <B>3) </B><B><U>PROPORTIONAL INTEGRAL ADAPTIVE (P.I.A.) TH110/111/132/135/140/141</U></B></div> <div> Each thermostat is equipped with a proportional integral adaptive (P.I.A.) controller which reduces temperature variations and allows the correction of the discrepancy caused by the variation of the heat energy release charge. In simpler terms, it provides a much more accurate temperature regulation while increasing user comfort.</div> <bR> <div> <B>WHY DOES THE P.I.A. CONTROLLER SHOW A BETTER PERFORMANCE ?</B></div> <div> Contrary to a conventional controller which defines heating cycles based on the current temperature, the P.I.A. controller determines heating cycles by taking into account the history of the temperature inside the building. Consequently, it adapts its control parameters to the analysis of past data.</div> <bR> <div> <IMG SRC="09f4c190.gif" border=0 width="76" height="25" ALIGN="BOTTOM" HSPACE="0" VSPACE="0"></div> <bR> <div> <B>CONVENTIONAL CONTROLLER :</B><FONT SIZE="3" COLOR="#000080" FACE="Arial" > </FONT></div> <div> If the outside temperature is mild, during the autumn or spring for example, the furnace will start its heating cycle at full power. It will therefore generate a temperature increase in the center of the room much faster than along the walls where the thermostat is installed. Since the thermostat will be slow to react, the room will be overheated.</div> <bR> <div> <B>P.I.A. CONTROLLER</B><FONT SIZE="3" COLOR="#000080" FACE="Arial" ><B> </B></FONT><B>:</B></div> <div> In the same situation, the P.I.A controller will define the power required before the beginning of the cycle. It will calculate, based on the heating system's past performance, the duration of the heating cycle required to optimize the room temperature variation. Contrary to a traditional controller, it will react much faster. </div> <div> The P.I.A. controller optimizes the temperature variation in the room based on the number of cycles per hour authorized by the heating system.

It is therefore recommended to use a proportional control system which sends to the heating system only the power required. User comfort will be much greater than with a conventional system which can only send 100% of its power. </div> <bR> <div> <IMG SRC="0a5e7230.gif" border=0 width="231" height="35" ALIGN="BOTTOM" HSPACE="0" VSPACE="0"></div> <div> Thermostats allow energy savings because of their ACCURACY and their various OPERATING MODES.
