DA PNEUMATIC VERTICAL MOUNT THERMOS
A pneumatic thermostat is a step-control device with a spring-loaded diaphragm which moves in response to changes in air pressure when the control knob is turned. A red zone shows the zone in which heating is turned off and a yellow zone indicates when cooling is in operation. It is a direct acting thermostat with a vertical mount, and single temperature. The operating voltage of this thermostat is 208~240 VAC/V/Hz, k type connection, N.O.C. Heating elements are required by this thermostat.
Thermostat: Johnson Controls 3561 Vertical Mount, Single Temperature High Volume Output Thermostat
A small, rugged thermostat designed for severe conditions, the DA-3561 can handle up to a 7-day program with free cooling. Its pneumatic operation accomplishes fast response time and accurate, reliable control. Heat anticipator helps delay heat on cold start-ups from gas or electric heaters. This thermostat is ideal for a variety of heating and air conditioning systems including boilers, fireplaces, furnaces, hot water tanks and heat pumps.
Direct acting pneumatic thermostats are designed for use with air conditioning and heating systems. Capacities range from 5 to 125 horsepower. All direct acting thermostats come with a complete installation and operating instruction manual and the industry standard of five-year warranty on all materials and workmanship.
Vertical mounting. Provides individual control of each heating zone in single zone hydronic systems by outputting direct acting mechanical pressure. It is suitable for radiant floor heating for low to medium peak/high continuous loads in multi-zone systems when used with SWB, SWC, SCD or SLE zones.
Vertical, pneumatic thermostat is used to control the flow of air at a building's heating or cooling system. The thermostat has two adjustment bubbles and mounts vertically.
The GM Series Horizontal Mount Digital Thermostat is designed for direct horizontal to vertical connection without use of an adapter. It features a see-through display to facilitate monitoring and control of goods temperature, and is suitable for use with constant volume air conditioning equipment.
The VTVT has a 1/8" thick bimetallic element for extra accuracy and stability. The vertical mounting makes the element visible and easy to install and remove. The bore diameter is 1 inch with a flat and large mounting flange with predrilled holes make the preparation quick and easy.
The Johnson Controls 3561 is a vertical thermostat, direct acting with a maximum load of 750 watts and a voltage rating of 24 V AC/V DC. This thermostat is used as a control for heating and cooling systems. It is suitable for commercial and residential applications such as heat-pump loops or ac halogen fan coils, and free-standing gas heater service valves.
This thermostat has many applications. It can be used to control the temperature of air or liquids. The use of thermocouples for temperature measurement is recommended in place of RTDs because the effect of the switching frequency (50/60Hz) on the response time is smaller.
A thermostat, such as the Johnson Controls 3561, is an integral part of a heating and cooling system because it allows for accurate control of the temperature. If you require precise control over a single temperature or a greater control range then a single-set-point thermostat may be exactly what you need to satisfy your needs.
