Amplifiers:

A1044 (min. 40° to 80° F/ max. 80° to 140° F)

A1044C (min. 20° to 60° F/ max. 80° to 140° F)

A1044D (min. 20° to 60° F/ max. 35° to 75° F)

A1044E (min. 20° to 60° F/ max. 60° to 120° F)

A1044L1, A1044CL1, A1044DL1, A1044EL1, A1044FL1 -

above ranges with adjustable low fire start duration

NOTE: Amplifier and Discharge Temperature Sensor must

have same temperature range to be compatible.

Discharge Temperature Sensors: use with Mixing Tube

TS144 (min. 40° to 80° F/max. 80° to 140° F)

TS144C (min. 20° to 60° F/max. 80° to 140° F)

TS144D (min. 20° to 60° F/max. 35° to 75° F)

TS144E (min. 20° to 60° F/max. 60° to 120° F)

TS144F (min. 40° to 60° F/max. 60° to 95° F)

Mixing Tubes: used with Sensors

MT1-9 or MT2-9 (9" length)

MT1-12 or MT2-12 (12" length)

MT1-23 or MT2-23 (23" length)

MT1-28 or MT2-28 (28" length)

MT1-57 (57" length)

Valves:

M411 (3/8" & 1/2" pipe size)

M511 (1/2" & 3/4" pipe size)

M611 (3/4" & 1" pipe size)

MR212D (1", 1¼", 1½ pipe size)

MR212E (1½" & 2" pipe size)

MR212G (2½" & 3" pipe size)

MR212J (4" flanged)

MR212D-2, E-2, G-2 & J-2 (same pipe sizes as MR212D-J

except used for 2-speed blower or dual fuel operation)

NOTE: M (Modulator) valve requires an upstream pressure

regulator for low fire & high fire settings.

MR (Modulator/Regulator) valve requires no

upstream pressure regulator up to 5 psi inlet.

Selectrastat (Senses & Selects):

T244 (55° to 90° F)

T244A (40° to 80° F)

or optional pair to replace Selectrastat:

Space Temperature Selector:

TD244 (wall mount 55° to 90° F)

TD244A (wall mount 40° to 80° F)

TD244P (panel mount 55° to 90° F)

TD244AP (panel mount 40° to 80° F)

Space Temperature Sensor:

TS244 (55° to 90° F)

TS244A (40° to 80° F)

NOTE: Space Temperature Selector and Space

Temperature Sensor must have same

temperature range to be compatible.
