control
In order to increase continuous operation of the unit in low latent heat applications and avoid the rise
of temperature after thermostat OFF, the thermostat control will be changed when using field settings
16(26)-2-03 & 16(26)-2-04.
Thermostat ON
P ∆Trs ≥ 0.5 °C (No change from standard setting)
