Electronic Modulation Gas-Fired Temperature Controls/Direct Fired Applications

DESCRIPTION

Selectra ® systems from Maxitrol maintain precise, stable

gas-red temperatures. Selectra’s unique electronic
Modulator or Modulator-Regulator valves control gas ow
with instantaneous response and continual adjustment.
They are the superior alternative to mod motors and
buttery valves.

OEM or retrot applications include environmental climate
control, as well as industrial or commercial heating
processes. Standard temperature adjustment range is 55º
to 90ºF. All fuel gases are compatible with capacities up to
30,000,000 Btu/h.

Available standard companion electronics include
temperature selectors, ampliers, and temperature
sensors, in a variety of congurations. The amplier
supplies output voltage to the M/MR valve (see Figure 1).

MAKE UP AIR APPLICATIONS

Series 14 System

Selectra ® Series 14 systems are designed primarily

for make-up air heating, as components of direct red
equipment.

A discharge air temperature sensor is mounted within a
mixing tube housing.

Ampliers are available with low-re start duration and
integral or remote temperature selection.

Options:

• A room override thermostat provides space tempera-
ture control by raising the discharge air temperature to
a preselected point - when used in conjunction with the
remote temperature selector.

• An inlet air sensor (and mixing tube) provides inverse

change in discharge air for each degree change in

inlet air - when installed in a convenient duct location
upstream of the burner.

• A dual temperature selector replaces TD114 to provide
dual control for door heaters or other applications such
as paint spray booths.

SPACE HEATING APPLICATIONS

Series 44 System

Selectra ® Series 44 systems are designed primarily for

space heating, as components of direct red equipment.

A wall mounted Selectrastat ® senses space temperature
and has an integral selector with either a 55º to 90ºF or 40º
to 80ºF range. A discharge air temperature sensor (and
mixing tube) is a means of limiting the minimum and maxi­mum discharge air temperature.

Ampliers are available with low-re start duration feature.

Option:

• Instead of a Selectrastat, a separate remote tempera-
ture sensor and selector can be substituted.
