EDV - Designed for mixing or diverting flows in
various water based heat or cooling transmission
systems, such as radiator loops, floor heating, etc.
Add appropriate operator.
OPSK - Consists of the reliable MTW direct
mounting thermostat. It controls room temperature
by regulating the amount of air and steam in the
radiator.
MTW - Non-Electric direct mounting thermostat
with a numerical window reading that corresponds
to various temperatures. May be limited or locked
if required. Features heat diffusing rings to dissi-
pate heat away from sensor for added accuracy.
MTWZ - Non-Electric, fully automatic thermostat
with valve mounted temperature setting dial and
remote sensor.
ENTL B46000 - Non-Electric, fully automatic
remote thermostat with built-in remote sensor and
temperature setting dial.
ENTLZ B56000 - Non-Electric, fully automatic
thermostat with separate remote sensor and remote
temperature setting dial.
VMC (normally closed) & VMO (normally open) -
24-Volt controller designed for use with the Macon
NT series valves. Ideal for control of radiators, fin-
tube, zones, fan coils, heat pumps, radiant floor,
etc...
VM 2-10V is used to regulate valves in heating
and cooling systems using a built-in processor.
ZMC ES (End Switch - normally closed) is con-
trolled by a 24V room thermostat with two-point
output or pulse-width modulation.
ZMC-DDC (Proportional - normally closed) is
used to regulate valves via a central DDC system
or by a room thermostat.
MVA 2-10V - Motorized Electric zone control
actuator for controllers with continuous output in
conjunction with single-room control systems.
