Tekmar Controls

The Boiler Control 284 is designed to operate up to four boilers to accurately maintain a target water temperature. The 284 operates both condensing & non-condensing boilers that are either modulating, single stage or two stage to provide a flexible, cost effective mixed boiler plant solution with better system performance. The target water temperature is based on outdoor temperature reset or a fixed setpoint for space or process heating applications. Additional loads supplied by the 284 include domestic hot water & fixed setpoint heating. Boiler equal run-time rotation, stand-by primary pump operation & pump exercising all increase boiler plant reliability. The 284 communicates with a Building Automation System (BAS) using BACnet® or Modbus® for remote monitoring & adjustment capability. tekmarNet® Thermostats or a tN4 Gateway 485 can be added to optimize system performance & provide remote monitoring capability.

The Power Manager 346 is designed to allow non-tekmar products to interface with a tekmarNet® 4 communicating heating system. It can be used in applications that use 3rd party thermostats, zoning devices, or mechanical equipment that requires a hot water demand from the boiler system. This product provides demand inputs for up to 4 different reset water temperatures (high temp, low temp 1, low temp 2, low temp 3). It has the capability of switching 3 pump outputs and provides wiring for up to 3 tekmarNet® 4 devices, as well as the 4 separate demand inputs to create a heat call on one of up to 4 possible reset water temperatures.

The Mixing Control 356 is designed to operate a mixing pump to control the temperature in a hot water heating system using Outdoor Temperature Reset. It can be used in applications ranging from in-floor radiant to commercial baseboard systems for boiler protection with full reset. This control regulates a single heating water temperature through Outdoor Temperature Reset. It provides mixing by speeding up or slowing down a single permanent capacitor (standard wet rotor) circulator.

The Mixing Control 360 is designed to operate a mixing valve using Outdoor Temperature Reset. It can be used in applications ranging from in-floor radiant to commercial baseboard systems for Boiler Return Protection with full reset. This control regulates a single heating water temperature through Mixing Outdoor Reset. It controls the mixing by opening or closing a floating action type mixing valve actuator (3 or 4 way valves), and also provides control of the mix system pump.
