(Option 05) Optimum Start
When enabled, this uses current ambient temperature, the
next scheduled setpoint and heat gain data captured by the
device to adjust the thermostat setpoint early, so the ambient
temperature is at the required level when the next event starts.
Delayed Start
When enabled, this uses current ambient temperature, current
event setpoint and heating characteristics of the environment
to delay implementation of the setpoint if the ambient
temperature is already close to it, therefore saving energy.
(Option 06) Valve Protection Time
In some hydronic heating systems it may be required to protect
the valve by operating it for a given time. When enabled, this
maintenance feature ensures that each relay output is operated
for at least one (1) minute each week.
