Dynamic Set Point and omission of inertia tank
The control system of the YLCA/YLHA PLUS 5 to 27 includes the Dynamic Set Point and Omission of
Inertia Tank.
Dynamic Set Point: Modifies the set point for the control of the water temperature according to the outdoor
temperature. The objective is to prevent an excessive difference in temperature between the interior and
exterior of the air-conditioned area. If there is a large difference, this may result in discomfort or thermal
shock for the users entering and leaving the area and could even endanger their health. In addition, this
function, which increases the set point during the summer cycle and reduces it in the winter cycle, sig‐
nificantly contributes to the system's energy savings.
Omission of inertia tank: This function increases the temperature differential which, when added to the
control set point, adjusts the stop/start cycles of the compressor when the unit is operating with a low
load. It uses the length of the compressor operating cycles as reference. Therefore, when the water
temperature falls quickly, it delays the stopping of the compressor by simulating the inertia tank function,
thus avoiding too many stop / start cycles of the unit. This function, although slightly reducing the accuracy
of the water temperature control, makes the use of the inertia tank unnecessary.
