Johnson A419GBF-1C 24VAC Single Stage Temperature Control
The A419 series controls are single-stage, electronic temperature controls with a Single-Pole, Double-Throw (SPDT) output relay. They feature a lockable front-panel touchpad for setup and adjustment, and a Liquid Crystal Display (LCD) for viewing the temperature and status of other functions. A Light-Emitting Diode (LED) indicates the controls? output relay On/Off status. The A419 controls are available in 24 VAC or 120/240 VAC powered models. The A419 controls have heating and cooling modes, adjustable setpoint and differential, an adjustable anti-short cycle delay, and a temperature offset function. The setpoint range is -30 to 212°F (-34 to 100°C). The controls feature remote sensing capability and interchangeable sensors. The A419 controls are available in either NEMA 1, high-impact plastic enclosure suitable for surface or DIN rail mounting or NEMA 4X watertight, corrosion-resistant surface-mount enclosures.
Grundfos Alpha 15-55F/LC Circulator Pump (59896832) is a variable speed circulator with a built-in check valve and Line Cord. With its permanent magnet motor design, this energy efficient circulator reduces power consumption by 50% or more. The unique patented AUTOADAPT feature of the Grundfos 15-55F/LC model controls pump performance automatically within defined performance range, ensuring lowest possible energy consumption without sacrificing comfort. Conveniently installed line cord allows to plug the circulator right into the electrical outlet, bypassing unnecessary wiring.

1" NPT Inlet Ball valves and 3/4" outlets. This pre-assembled distribution assembly with Return distribution manifold including Built-In Shut-Off Valves suitable for Thermo-Electric Actuators, and Supply distirbution manifold including Manually-Adjustable Balancing Valves. MAX working pressure: 150 psi. MAX temperature 210 F.
Distribution manifolds for radiant panel systems are used to optimally distribute the heating fluid in floor
heating system circuits and ultimately improve the control of heat emission from the panels. The manifolds
ensure that the flow of each circuit is regulated precisely and also control the shut-off, venting and automatic
removal of air from the system.
The AutoFill™ automatic filling valve is a pressure reducing valve with
a compensating seat, an inlet filter, a shut-off valve and a check valve.
It is installed on the water inlet piping in sealed heating systems, and
its main function is to maintain the pressure of the system to a preset
value, automatically filling up with water as required. This valve has been
designed as pre-adjustable, which means it can be adjusted at the required
pressure value before charging the system. After installation, during the
filling or topping-off phase, the water feed will stop automatically when the
set pressure is reached. There are no levers to flip or valve to close. Preassembled with the backflow preventer, it features an atmospheric vent
which is designed to protect drinking water systems from return flow, caused
by back-siphoning or backpressure, of contaminated fluids. The 573 series
has been specifically certified to standards CSA B64.3 and ASSE 1012.
Caleffi Series 5213 Scald Protection Three Way Mixing Valve
Adjustable, anti-scald thermostatic mixing valve.
The thermostatic mixer is used in systems producing domestic hot water or in radiant panel heating systems. Its function is to maintain the temperature of the mixed water supplied to the user constant at the set value when there are variations in the supply conditions of the incoming hot and cold water.
The valve has been specifically certified to ASSE 1017.

Glass reinforced nylon internal element.
Max. working pressure: 150 psi.
Working temperature range: 32—250°F.
In heating and air conditioning control systems, the circulation of water containing impurities may result in rapid wear and damage to components such as pumps and control valves. It also causes blockages in heat exchangers, heating elements and pipes, resulting in lower thermal efficiency within the system. The dirt separator separates off these impurities, which are mainly made up of particles of sand and rust, collecting them in a large collection chamber, from which they can be removed even while the system is in operation. This device is capable of efficiently removing the smallest particles, with low head loss.
