Optimum start control
Heating
Synco RMH760
Achieve Comfort or Precomfort setpoint at the start of use (per time
switch).
– Precise reaching of the desired temperature conditions.
– Prevent user interventions that waste energy.
The heating circuit is switched on at an earlier time. The main
parameters are the outside air and room temperatures (measured or
calculated). 2 cases:
• Room temperature sensor available: Controller learns the heat up
time per Kelvin room temperature.
• Room temperature sensor not available: Controller uses a room
model to calculate the room temperature; manual entries required.
Applies only when no room temperature sensor is available:
– Optimization mode is set to "With room model".
– Building time constant is entered.
– Room temperature rise is entered.
Function is disabled as factory setting by setting the maximum
forward shift to 0 hours.
Enable function by entering a value > 0 hours.
