Part number 129209
M3 Boiler
Probe 1:
Is in the top of the tank, and controls the burner. Provides outlet temperature.
Probe 2
: Is wired but lose and field installed in the boiler HWR piping.
Probe 3
: Is in the flue.
Alarm_AL2
: Alarm on any failure.
Burner_Relay1
: Burner
Relay2
: Alarm dry contact, goes to terminals A1 & A2.
Relay3
: Isolation Valve control, used with OnTrac group control. Terminals labeled
CIRCULATOR 1 & 2.
Modulation Rate
: Modulation rate, Low fire = 0, High Fire = 100.
Discrete connections:
External Enable:
Terminals R1
– R2, Jumper to enable. Heater ships with jumper on
this. An external enable/disable can be attached to this. This is a low current, low
voltage contact. It is advised to use a contact with gold plating. If not available, use 2
contacts in parallel.
Alarm
: A1 & A2 (Output from Heater) Closed = ALARM.
Remote Proving
: C1 & C2. Ships with factory jumper. Open will prevent burner from operating. Keeping
this open will create a lockout condition that will require user intervention.
Remote Equipment / Burner ON
: Contact that will close P1
– P2 during a heating cycle. Open, the heater
is not calling for heat.
No Setpoint Input
: There is not a discreet method to send a setpoint signal to the M3 boiler.
No Modulation Input
: There is not discreet way for a building automation system to control the modulation
(firing rate) of the Conquest.
