Cemline Cem-trol™ Solid State Water Heater Control Module incorpo-rates operating and limit functions in one solid state controller. Thiscontroller replaces the current controls used on Cemline PackagedWater Heaters. The controller features an LCD display of the tempera-ture and on board operating PID temperature control along with hightemperature safety cut offs and alarm indications. The Cem-trol™ sim-plifies the control of Cemline Packaged Steam and Boiler Water FiredWater Heaters, enhances the look of the product, and follows theindustry trend to solid state controls.

Cem-Trol™ Solid State Water Heater Controller

Features:PID Control Signal

• PID Control Signal used to modulate an electronic valve or used to control an electronic-pneumatic transducer modulating an air operated control valve.The PID controller allows for precise temperature control of the water heater.

On-Off Switch• Allows for local on/off and is convenient for service in the unlikely event of

service.

Single Point Wiring• Only one 120 VAC connection required to the unit, integral circulation

pump pre-wired to control panel.

Temperature Readout• The Cem-trol features an easy to read LCD digital readout of the water

temperature.

High Temperature Set Point• Closes control valve in event of a high temperature situation.

Secondary High Temperature Set Point• Opens an optional water solenoid to dump over heated water down the

drain.

Remote Temperature Setting• Building Automation System can remotely set the operating temperature

using a 4-20 mA signal.

Remote Temperature Readout• Building Automation System can remotely read water temperature via a

4-20 mA signal.

Control Valve/Traps

Cemline SWH water heaters can be furnished with air operated, pilotoperated or electronically operated control valves. All valves are normally closed, that is closed when no air or pilot pressure or electricsignal is present. The valves will close on loss of building power.

A pilot operated valve can be used with steam as the energy source. Pilot operated valves are not suitable when boiler water is the heating medium.

Pilot operated valves use steam pressure as the energy to modulate the control valve. Steam from upstream of the valve is directed into a pilot valve.This pilot valve has an adjustable set point and temperature-sensing bulb in the heated water. The pilot valve compares the set point to the sensed temperature and regulates the amount of steam passing through the pilot to the diaphragm in the bottom of the control valve.The steam pressure on the diaphragm opens the control valve. A pilot operated valve has a constant bleed line leading from the diaphragm to the downstream side of the valve.When the pilot valve senses that the desired temperature is reached it closes; this does not allow any more steam topressurize the diaphragm in the bottom of the control valve.The bleed line allows any steam pressurizing the diaphragm to be relieved and the valve closes. In the event of high temperature or loss of building power the limit control closes the steam line from the pilot to the valve, which closes the valve.

Electronically Operated Control Valves

Electronically operated control valve can be used for either steam or boilerwater.

Electronically operated control valves use a solid-state temperature sensor,which is wired to the CEM-TROL™ electronic control module. The CEM-TROL™has an adjustable temperature set point. The CEM-TROL™ compares the setpoint with the sensed temperature and sends an electric signal to a magneticlinear actuator on the control valve. The magnetic linear actuator modulatesthe control valve and regulates the amount of steam (boiler water) throughthe valve to maintain the set point of the controller. When the set point isachieved the controller sends a signal to the valve actuator and the valvecloses. In the event of high temperature or loss of building power the limit con-trol closes the electric power to the controller, which closes the valve.

Cemline provides float and thermostat traps for both the drip and main trap.

Float and thermostat traps are acknowledged as the correct traps to use with continuously modulating control valves. Float and thermostat traps provide immediate drainage of condensate and include a built in thermostatic air vent for venting air. The drain orifice is designed to provide a water seal and eliminate the loss of any live steam under all load conditions. Float and thermostatic traps should not be used to lift condensate.

Air Operated Control Valves

Pilot Operated Control Valves

Traps

An air-operated valve can be used with either steam or hot water as the heat-ing medium. Air operated valves are normally used in buildings when buildingcontrol air is available.Air operated valves use building control air pressure to modulate the controlvalve. A solid-state temperature sensor is wired to the CEM-TROL™ electroniccontrol module, which has an adjustable temperature set point. The CEM-TROL™compares the set point with the sensed temperature and sends an electroniccontrol signal to an electronic-pneumatic transducer. The electronic-pneumatictransducer converts the electronic control signal to a 3 – 15 psig pneumaticcontrol signal. The CEM-TROL™ regulates the amount of air that passes tothe electronic-pneumatic transducer thereby modulating the control valve.This allows steam (boiler water) to pass into the heater coil to maintain theset point of the controller. When the set point is achieved, no air is passedthrough the electronic-pneumatic transducer and the valve is closed. In theevent of high temperature or loss of building power, the limit control willclose the airline to the valve and vent any air in the actuator to atmo-sphere that closes the valve.
