8.5 Typical Factory Settings of Parameters
for MicoFlame Grande BTC 1 (78-0017)
This modulating MicoFlame is equipped with the
Camus version of the Tekmar MPA control.
Summary of 8 Modes of Operation
Mode 1
- For setpoint control at heater inlet
sensor. Use for hydronic constant
setpoint heating or domestic hot water
applications.
- External heat demand or constant
pumping required.
Mode 2
- For setpoint control at system sensor
- Ideal for monitoring constant hot loop or
for pool heating
- Intermittent pumping povided.
Mode 3
- For DHW control with tank sensor.
Controls to boiler inlet sensor.
- Intermittent pumping provided
Mode 4
- For hydronic heating with outdoor reset.
Temperature control at boiler inlet
sensor with proportional modulating
logic.
Mode 5
- For hydronic heating with outdoor reset.
Temperature control at system sensor
with selectable P.I.D. or proportional
modulating logic.
- Intermittent pumping provided
Mode 6
- External analogue 0-10VDC signal
generates temperature target. Setpoint
temperature control at heater inlet
sensor using proportional modulating
logic.
- Intermittent pumping provided
Mode 7
- External analogue 0-10VDC signal
generates temperature target. Setpoint
temperature control at system sensor
with selectable PID or modulating logic.
- Intermittent pumping provided.
Mode 8
- External analogue 0-10VDC signal
closes the stage contacts to initiate
heater. Modulating output of the control
follows the analog external input signal.
Temperature is controlled remotely
independently of local settings. Boiler
max. setting remains functional.
- Intermittent pumping provided
