The tekmar One Stage Setpoint Control 150 is a microprocessor-based control that

can be programmed

to maintain a ﬁxed setpoint temperature by cycling a heating or cooling device using either bang-bang

or Pulse Width Modulated (PWM) output control.

This reliable and versatile control has a very wide setpoint range, an adjustable differential and time

delay that makes it useable in many different applications. The control has a digital LCD window that

normally shows the actual sensor temperature and can be used to view the setpoint as well as the other

programmed settings.

A Universal sensor 071 is supplied with the control. The wire to the sensor may be extended up to 500 ft.

(150m) by standard 18 AWG low voltage wire. The display will indicate a sensor fault whenever the

sensor is either open or short circuited.

Technical speciﬁcations

Setpoint — -40 to 239°F (-40 to 115°C)

Differential (Bang/Bang) — 1 to 40°F (1 to 22°C)

Differential range (PWM) — 3 to 40°F (2 to 22°C)

Time delay (Bang/Bang) — 0 to 19 min. 50 sec.

(10 second increments)

Cycle length (PWM) — 30 sec. to 19 min. 50 sec.

(10 second increments)

Operating mode — Heating/Cooling

Temperature scale — Fahrenheit/Celsius

Programmed settings — Ten year memory

backup

• When the One Stage Setpoint Control 150 is powered-up

the digital display will show all of the display elements. The control

will then monitor the sensor temperature and display it in the digital display. (See diagram)

Bang - Bang Operating Mode

Bang-Bang control outputs turn equipment on when there is a demand for heating

or cooling, and then shut it completely off when the demand is satisﬁed.

• If the control is programmed for “Heat”

in this mode, it turns on its relay and

the “HEAT” display element when the sensor temperature is (a) — 1/2 the

differential setting below the setpoint,

and

(b) — the delay has timed out.

When the sensor

temperature rises 1/2 the differential setting above the

setpoint, the relay switches off , the “HEAT” display element turns off and the

delay starts to time out.

During the time out period, the Delay/Cycle pointer

will ﬂash if heating is needed.
