Details - Setpoints
MESSAGE NO: S3-09 APPLIES TO: Selected Control Module
DEFAULT VALUE: $0.05 VALUE RANGE: $0.01 to $0.50
DISPLAY MODE: Advanced RESTRICTIONS: None
This function sets the COST PER kWh. This value is used to calculate Energy
Cost.
MESSAGE NO: S3-10 APPLIES TO: Selected Control Module
DEFAULT VALUE: off VALUE RANGE: on, off
DISPLAY MODE: Advanced RESTRICTIONS: None
This feature staggers the power up of heater circuits to eliminate tripping of the
main breaker. For all Control Modules with this value set to “on” the following
sequence occurs at power up based on a minimum of 10 circuits. About 10% of the
heaters circuits are turned on, there is a one minute delay and then the next 10%
are turned on until all circuits are energized.
Note: Stagger Start is a module setpoint, if this setpoint is set to “on”, Stagger
Start will only be applied to the selected module. Stagger Start will not be applied
to the whole system.
MESSAGE NO: S3-11 APPLIES TO: Selected Control Module
DEFAULT VALUE: 0 VALUE RANGE: 0 to 10, Master 1 to 10,
Remote 1 to 10
DISPLAY MODE: Advanced RESTRICTIONS: None
This function sets the number of ambient sense heaters for the selected control
module. Refer to Appendix E for the operation details of this message.
MESSAGE NO: S3-12 APPLIES TO: Interface Module
DEFAULT VALUE: None VALUE RANGE: None, HT 1-1, HT 2-1 to
HT 30-1, MR100
DISPLAY MODE: Advanced RESTRICTIONS: MR100 Interface Module
This function sets the global ambient RTD for the heaters selected for freeze
protection applications. Refer to Appendix E for the operation details of this
message.
MESSAGE NO: S3-13 APPLIES TO: Interface Module
DEFAULT VALUE: N/A VALUE RANGE: -50°C to 500°C
-58°F to 932°F
DISPLAY MODE: Advanced RESTRICTIONS: MR100 Interface Module
This read-only message appears only when the AMBIENT SENSING HEATER
(msg. S3-12) is not selected as None. The displayed value is the actual measured
temperature of the global ambient RTD sensor. If the temperature is outside the
value range, “RTD OPEN” or “RTD SHORT” is displayed. Refer to Appendix E for
the operation details of this message.
MESSAGE NO: S3-14 APPLIES TO: Interface Module
DEFAULT VALUE: On Board VALUE RANGE: RTD Sampler 0 to 15, On
Board, RTD Transmitter
DISPLAY MODE: Advanced RESTRICTIONS: ML100 Interface Module
This function sets the type of RTD board used for the control module.
When the option “On Board” is selected, the control module uses the RTD board
directly mounted on itself to measure heater temperatures.
If the option “RTD Sampler x” is chosen, the control module uses the temperature
measurements from “RTD Sampler x” to control heaters. Here, x is the address of
the RTD Sampler. The RTD Sampler is an independent temperature-measurement
device and is usually located far away from the control module. The temperature
