CONTROL SYSTEM SPECIFICATIONS
GENERAL CRITERIA:
•
Main control module will control electronic pilot ignition,
main burner ON/OFF operation, and Main Flame modulation.
•
Main control module will also house an RF reception circuit.

2-sets of dry contact inputs (switch inputs) allowing ON/OFF
and HIGH/LOW operation (2-settings only).
•
Control can Learn up to 3 transmitter security codes
(3-transmitter LEARN memory).

SPECIFICATIONS
•
Operating Power:
1. 6V Battery Power:
-
4xAA Size – Intended for battery backup use.
-
Minimum operating voltage – 5.4VDC
•
Temperature Limit: 170-deg. F.
• RF Receiver Frequency: 303.8MHz
•
Ignition Trial Period: 50-60 seconds
•
Sense Voltage Thresholds (start with V-TC=0mV before
taking threshold measurements):
1.
Flame True = 12mV +/-1.5mV (judged while safety
magnet is powered by control)
2. TC-HOT (OK to transfer thermocouple power to Safety
Magnet) = 18mV minimum, multiple samples taken
every 5-seconds and compared with previous sample
set, if change less than +0.5mV, TC-HOT=TRUE.
Maximum allowable time control will power Safety
Magnet = 60-seconds.
3.
Flame False (Before TC-HOT=TRUE) = 10mV +/-1.5mV
4.
Flame False (After TC-HOT=TRUE) = 10mV +5mV/-0mV
•
Maximum Flame Failure Response Time: 30-seconds,
when used with approved fast-acting thermocouple.
•
Minimum Flame Failure Response Time: 10-seconds
1. 10-Second Flame Failure Response Time Logic:
-
Main Burner is turned to ON.
-
Normal pilot ignition sequence occurs.
-
Thermocouple output reaches FLAME=TRUE
threshold
-
Main Burner is Opened
-
At the same time the main burner is opened, a
10-second delay timer is started.
-
If the thermocouple voltage drops to below
FLAME=FALSE during this 10-second timer period,
THE MAIN BURNER SHALL REMAIN ON and THE
CONTROL WILL EMIT THE IGNITION SPARK
(follow normal sparking pattern).
-
If the thermocouple voltage recovers to above
FLAME=TRUE during the 10-second timer period, the
sparking will stop and normal operation will resume.
However, the 10-second timer WILL NOT be reset.
Furthermore, this event will NOT trigger the
re-ignition safety fault counter.
-
If the thermocouple voltage does not recover to
above FLAME=TRUE after the 10-second timer
period expires, the main flame will turn OFF and
the control will attempt to re-establish the pilot
flame again with the normal 60-second trial period.
Furthermore, this event WILL trigger the re-ignition
safety fault counter (3-attempts within 2-minutes).
-
The 10-second delay timer will only be reset when
the system is cycled to OFF, then to ON again.
•
Maximum Number of re-ignition attempts
1.
Automatic: 2 re-attempts within 2-minutes, 5-minute lockout
2.
Manual: 5 re-attempts within 2-minutes, 5-minute lockout
•
Spark Pattern: Interrupted (2-second spark, 1-second
sense window)
•
Flame Modulation Settings:
1. Switch operation – 2 settings (High & Low)
2. Remote operation – Continuously Variable
3. Low Flow Rate regulated by low rate set-screw in gas valve
4.
Main flame shall default to HI setting for 5-seconds
whenever turned ON before modulating to any other
setting.
•
