1.5 Extra temperature settings
• Pumping permission delay: This is the time that the unit must wait to
activate pumping after all the active zones have reached a temperature
above [Set point temp. -3°].
• Programmable limits: Two limits can be set to prevent set point
temperatures from being programmed above or below those values.
• Temperature warning: A temperate (±°C/°F) and a time are defined to
indicate when the overheating or low temperature warning is activated in
each zone.
• Temperature alarm: A temperature (±°C/°F) and a time are defined to
indicate when the overheating or low temperature alarm is activated in
each zone.
If either of those values are reached (±) and maintained for the set time,
the unit disconnects the heating in the zone causing the error. If the error
persists 3 minutes later, the remainder of the zones are automatically
disconnected. If the affected zones are the tank or the distributor, the unit
also stops the pumping.
• Alarma total por temperatura: Se define un valor (+°C/°F) y un
tiempo que indican cuando se activa la alarma por sobretemperatura.
Si cualquier zona alcanza esta temperatura y permanece el tiempo
establecido, el equipo desconecta el calentamiento de todas las zonas y
detiene el bombeo.
• Adaptive time: Automatic interval setting for warning and alarm
temperatures, when the user reprogrammes the setpoint values.
