RELAY SEQUENCING

HS SELECT - # of Heaters Enter 1 thru 4 for the number of heaters connected to relay out- puts 1 thru 4. This allows the RayTemp to correctly sequence heaters and record demand.

Firing Options

Four options for stage sequencing are available. Select number 1, 2,

 

3, or 4 as follows:

 

#1

No Lead/Lag: Stage 1 of heater #1 always fires first. The

 

 

remaining stages and heaters will fire in order as demand

 

 

increases.

 

#2

24-Hour Rotation: At midnight each day, the firing order is

 

 

rotated to the next heater. This distributes the work load

 

 

equally among all heaters.

 

#3

Lead/Lag & Rotate: With this option, heater #1 always fires

 

 

first, then the remaining heaters fire in rotation. Since some

flue

 

designs require heater #1 to fire first; this option meets this

 

 

requirement while still providing limited rotation.

 

 

 

US SELECT - Use 24volt on/off sensing. Do not use.
