The tekmar Steam Control 279 can operate a single on-off steam boiler or an on-off steam valve using outdoor reset. The control determines the on time of the boiler or valve based on the measured outdoor temperature and settings entered by the installer. A large LCD displays the current status and operating temperatures.
Control Description The Boiler Control 261 is a microprocessor-based two stage boiler control designed to regulate the supply water temperature from a single two stage boiler or two single stage boilers based on either outdoor air temperature or a setpoint demand. The 261 can stage and rotate two single fire boilers or it can stage a single Lo/...
Control Description The Boiler Control 264 is a microprocessor-based four stage boiler control. The 264 can provide either outdoor reset and setpoint operation or outdoor reset and DHW operation. The 264 stages and has Equal Run Time Rotation of the boilers and also operates the system pump and individual boiler pumps. One, two, three and four...
The pump sequencer 132 is designed to provide pump control for either stand-by or 2-stage operation.
In stand-by mode, the 132 automatically switches over from the lead pump to the stand-by pump during a pump failure. In 2-stage mode, the 132 turns on the second stage pump to meet additional flow requirements.
The tekmar Universal Sensor 071 has a zinc sleeve for fast response and a wide operating range. These sensors can be used in a multitude of applications. The 071 is supplied with 10 inches (250mm) of two conductor wire.
The Boiler Control 256 is a microprocessor-based control designed to regulate the supply water temperature from a single boiler based on the outdoor temperature. To avoid boiler short cycling and large temperature swings, the 256 is able to continuously adjust the boiler differential.
The tekmar Outdoor Sensor 070 includes a 10 kΩ thermistor which provides an accurate measurement of the outdoor temperature. The 070 sensor is protected by a white U.V. resistant PVC plastic enclosure.
