(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.
