Features
• Direct replacement for most fan & heat sequencing
functions.
• 24 volt input control
• Contacts designated M1 – M2 of a multi timing
sequencer will turn on first and turn off last, as required
by UL and CSA for electric heating applications.
• Five second on delay between all subsequent stages,
unless they function together.
Applications
The SUPCO Q Series and Sequencers
are field proven for controlling the
operation of heating elements and or
blower motors in electric, gas or oil heat
systems.
• Electric furnaces
• Heat Pumps
Recommended Sequencer Packages for Electric
Heating
Note 1: Auxiliary Contacts: In the above recommended packages,
during the ON cycle, the auxiliary contacts complete the
control circuit to subsequent 15S sequencers when more
than one 15S sequencer is required. The auxiliary contacts
may be any contacts in the first 15S sequencer except
those marked M1-M2.
Note 2: Fan Interlock: The recommended combinations which
contain more than one 15S sequencer include an extra set
of contacts for fan interlock. (These are the first contacts of
the second and third 15S sequencers.) A fan interlock is
required by Underwriters Laboratories in order to guarantee
that the fan will stay on until all elements are de-energized.
All of the M1-M2 contacts of each 15S unit would be wired
to the fan so that during the OFF cycle, the fan would stay
energized regardless of the timing sequence of each
package.
Note 3: Main Contacts, Electrical Ratings: 7FLA, 4LRA, 240 VAC
inductive or 30A, 240 VAC resistive or 30A, 240 VAC total
of inductive or resistive, with 7FLA, 240 VAC maximum
inductive.
Note 4: Control Voltage on Heater Terminals (H): 24 VAC nominal
(heater rated for 30 VAC/NEMA Class II circuit).

Sequencers
• Gas furnaces
• Oil furnaces
*Note all sequencers include a 240 volt heater, except the Q113 which has a 240 volt heater.
