ESCTDE2 Electronic Dual Hot Water Cylinder Thermostat The ESCTDE2 Electronic Dual Hot Water Cylinder Thermostat, has all the benefits of the standard (ESCTDE) product, but is programmable and enables the user to define the automatic override which lifts the water temperature to 60 C for one hour, to kill any legionella bacteria. A genuine energy saving product with safety protection and many other benefits. The illuminated display shows the temperature at or near the top of the cylinder as well as at the thermostat location to illustrate the degree of stratification. The programmable ESi Electronic Dual Cylinder Thermostat* is a revolutionary new energy saving product, developed exclusively by ESi. The hot water can be stored at any desired temperature between 25 C and 65 C. With the added advantage that the weekly automatic one hour boost can be set at a time that best suits the homeowner, using the internal clock. The boost then lifts the temperature to above 60 C to eradicate any legionella bacteria. This results in substantial energy saving compared to traditional systems storing the hot water at a constant 60 C. Electronic Dual Cylinder Thermostats The illuminated LCD display shows the current water temperature at two locations, and the user defined water temperature, while the red LED indicates that the unit is calling for heat. The sensitive electronic sensors operate at a far greater accuracy than a conventional oil filled mechanical dual thermostats, and do not need physical contact unlike traditional dual thermostats.

11 System Essentials ESRTM Mechanical Room Thermostat ESCTS Clamp-on Cylinder Thermostat The ESRTM mechanical room thermostat is an economical and simple to use room thermostat. Simply turn the mechanical control dial to your desired temperature to control your room temperature. This unit also produces an audible click when you turn the dial past the current temperature so you know when the system is being turned ON or OFF. The mechanical two wire thermostat is very easy to install and, by having volt free contacts, is suitable for systems with either a combination or normal boiler. If you have a three wire installation, simply cut back and make safe the neutral, and this two wire thermostat will give you years of faithful service. The ESCTS Cylinder Thermostat is configured specifically for the control of domestic hot water cylinders to suit householder lifestyles and can provide energy savings when set between the recommended 60 C - 65 C. Supplied complete with a mounting strap for the cylinder and a spring for the heating pipes, this unit is very easy to fit around either the cylinder or pipe. The bimetallic sensor ensures accurate hot water temperature control, while the large clear adjustable dial is easy to read and adjustable between 0 C and 80 C. The Cylinder Thermostat can be used to switch directly a wet central heating circulating pump or boiler, or to operate zone valves.

12 ESZV222/ESZV282/ESZV223 2/3 Port Zone Valves The ESi Controls range range of Motorised Zone Valves are easy-fit, with a simple clip on/off detachable actuator head and plug & play cable. The actuator has been designed to fit directly onto the valve body used by the market leader, and similar type bodies, with the two supplied screws - making it a quick-fit direct replacement for most households. The spring return valves have been designed to be used in commercial, industrial and domestic central heating systems which, when correctly wired with an appropriate room thermostat, cylinder thermostat and programmer, will control the water flow from the boiler to hot water, and from the boiler to central heating. ESZVA222/ESZVA223 2/3 Port Actuator Heads ESABV22 Auto Bypass Valve The ESABV22 is designed to maintain the water flow in central heating systems fitted with TRVs. They do this by maintaining the desired minimum flow rate through the boiler and limit circulation pressure when water paths may be closed. The ESABV22 reduces system noise that may be caused from TRVs or zone valves closing, eliminates pump impeller wear that can result from high flow resistance, enhances the life of the boiler heat exchanger by ensuring minimum flow rate at all times, and saves energy by only allowing flow through the bypass when needed. The use of an ABV is recommended by the UK Government (DEFRA) as Best Practice in the CHeSS guide to central heating systems. UK Building Regulations confirm that if a bypass is installed, an ABV must be fitted. 2 & 3 Port Zone Valves Auto Bypass Valve A direct replacement for the market leader Spring return action Manual lever for filling / draining the system Replacement actuator head and motor available and easy to exchange Detachable lead Quiet operation, minimum power usage Quick and easy to install 2 Port Zone Valve, 22mm & 28mm ESZV222 & ESZV282 3 Port Zone Valve, 22mm ESZV223 Actuator Head ESZVA222 (2 Port) ESZVA223 (3 Port) Supply Voltage VAC, 50/60Hz Power Consumption 5W Cable Length 1m - Plug in Cable Fluid Temperature Min-Max +5 C -+88 C Operating Temperature 5 C to +50 C Flow Direction As per arrow on valve body Auxiliary Switch Rating 250VAC 4A (2 Port) / 250VAC 3A (3 Port) Response Opening 12 seconds Response Closing 5 seconds Max Static Pressure 8 Bar Max Close-off Pressure 1 Bar (2 Port) / 0.69 Bar (3 Port) Complies with EN , EN , EMC Directive 2004/108/EC, LVD Directive 2006/95/EC 22mm compression fitting Reduces system noise 16 bar maximum pressure 120 C intermittent temperature High capacity flow, up to 50 litre per minute Wide differential pressure range, 0.05 to 0.5 Ensures a constant flow through the boiler Automatic Bypass Valve ESABV22 Connections 22mm Compression Joints Differential Pressure Range 0.05 to 0.5 Max Working Pressure 16 Bar Working Temperature 120 C Intermittent 12 ESi CONTROLS BROCHURE LANDSCAPE V5.indd 12 14/08/ :31
