PNEUMATIC THERMOSTAT 2 PIPE D.A. 1
The Honeywell 2-pipe direct acting pneumatic thermostat features a model 3106 controller that maintains a constant temperature within one degree of accuracy when matching a scroll type valve. The blown-air actuator opens or closes the contacts which control the heating, cooling, or ventilating system. The spring return acts to hold the contacts in their open position: all that is required to operate the valve is to allow air from the pump to gently press against the actuator to close the contacts
The Honeywell HVAC Pneumatic Direct Acting Thermostat features a dual temperature range and a 1-pipe design. The 2-pipe design is suitable for commercial systems and requires an external power supply. The pneumatic thermostat includes a self-diagnostic feature, which uses LED indicator lights in the event of a malfunction. It has a low voltage auxiliary input with automatic reset, which makes the thermostats compatible with any 24 VAC control system. A +/ symbol
The Honeywell Direct Acting Air Valve, Series 3106 is a direct acting, pneumatic thermostat designed to control gas, oil, or steam heaters. These valves carry high pressure and require an air supply of approximately 5 cfm at 50 psi (0.35 cfm/psi) and can be ordered to operate at any 2 of the 3 available pressure settings. These valves are available in 2 different configurations: 1 pipe (HVAC) application and 2 pipe (Ref
The Honeywell 3106 Pneumatic Thermostat is ideal for temperature control applications in HVAC, refrigeration and any other pneumatic device needing a pneumatic direct acting thermostat.
Honeywell's 3106PneumaticDirectActing Thermostat is suitable for use in pneumatic, mixed-gas, and single-phase systems. This pneumatic thermostat works on a 29 to 99 deg F temperature range. The control can operate over the range of 0 to 5 inH2O pressure for gas, and 0 to 10 psi pressure for electric or natural gas and up to 20 psi differential for other fluids. The Burglar resistant 1/8" solid
Honeywell's 3106 direct acting pneumatic thermostat automatically regulates maximum cooling or heating temperatures up and down, in response to varying heat loads. Outfitted with a highly visible differential pressure gauge, the 3106 also provides an accurate display of its setting and surrounding temperature. It's ideal for air conditioning systems, personal comfort cooling and refrigeration equipment, freezers, and boilers. Adjustable differential pressure gauge shows actual setting and surrounding temperature; large equal to/below/above balls indicate
The Honeywell 2 Wire pneumatic thermostat is for use in heating and air conditioning duct systems. It is adjustable for control of whole house systems or individual rooms. The operating pressure is 28" wc to 100" wc. 120 Volts, 5 Watts, 4-1/8"W x 2-3/4"H x 2-1/2 to 3-1/4"D.
