Johnson Controls Single Stage Digital Temperature Control
Johnson Controls Single Stage Digital Temperature Control (120/240v SPDT)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.$73.90 -

Johnson Controls Hot Water Cutout Temperature Control
Johnson Controls Hot Water Cutout Temperature Control w/ Manual Reset (100-240F)Johnson Controls A19 Series temperature controls are designed to cover a broad range of uses for heating and general purpose requirements. Controls have SPST contacts which open on temperature increase or they may be supplied in single-pole, double-throw contact action. Various control ranges are available to cover working temperatures from -30 to 550° F (-34 to 288° C). Closed tank fittings and bulb wells are available for immersion applications. These controls are designed for open low and open high applications. Where critical or high value products are to be maintained within a specific temperature differential, a single control should not be applied to function as both an open low and open high control. In these applications, a separate backup control with alarm contacts should be wired to indicate when the back-up control operates.$78.07 -

Fernox Express Boiler Comissioning Kit
Fernox Express Boiler Comissioning KitGood practice dictates that hydronic central heating systems should be thoroughly cleaned and flushed before installing a new boiler, after which a chemical inhibitor should be added to ensure the system is protected from corrosion, scale and sludge build-up. These procedures should also be employed when major work is carried out on a system. A clean, protected system helps ensure that the heat generated by the boiler is transmitted efficiently into the house over the long term
- Maintain the design specification and energy efficiency
- Restore energy efficiency
- Inhibit the formation of scale and sludge
- Minimize corrosion of system metals
- Product code: 59480

Fernox Total 1" Magnetic Debris Filter
Fernox Total 1" Magnetic Debris FilterThe revolutionary Fernox Total Filter TF1 is a unique hydrocyclonic and magnetic in-line filter that removes and contains magnetic and non-magnetic contaminants from central heating systems. Easy to install with no additional parts needed, the Total Filter TF1 has also been designed as a dosing point for the Fernox 'F' range of chemical water treatment products to ensure the system's long lasting performance.
The new Fernox TF1 in-line filter can be connected directly onto 22mm and 28mm pipe work using the valve fittings provided and can be positioned flush to a wall in existing pipe work. Once installed, it can be cleaned in seconds and easily and without having to disassemble or remove the unit.
"The Fernox TF1 has been specifically developed to provide installers with an easy to fit filter that helps maintain the performance and longevity of a central heating system," explained Francine Wickham, European Marketing Director. "The hydrocyclonic and magnetic filters remove and contain contaminants so that the system can work effectively. The Fernox TF1 filter then provides an easy way for installers to dose the system for long term protection."
All Fernox TF1 filters are manufactured in the UK and each one tested so installers can be assured of performance and reliability every time.
Hydrocyclonic and magnetic in-line filter
- Unique action, removes all contaminants magnetic and non-magnetic
- Fits vertical and horizontal pipe work
- Dosing point for Fernox ‘F’ range products
- Cleaned in seconds without removal or disassembly
