Time Proportional Integral Mode (Tpi) - EPH Controls RFRB V2 Installation And Operation Manual

P0 1 Operating Mode

Time Proportional Integral Mode (TPI)

When the thermostat is in TPI mode and the temperature is rising
in the zone and falls into the Proportional Bandwith section, TPI
will start to a ect the thermostats operation. The thermostat will
turn on and o as it gains heat so that it doesn't overshoot the
target by too much. It will also turn on if the temperature is falling
so it doesn't undershoot the target which will leave the user with a
more comfortable level of heat.
There are 2 settings that will a ect the thermostats operation
1. The number of heating cycles per hour
2. The Proportional Bandwith
CyC – Number of Heating Cycles per hour
This value will decide how often the thermostat will cycle the
heating on and o when trying to achieve the target temperature.
You can select 2/3/6 or 12.
