RD1606/M Hard-Wired Steam Boiler Control

  • On/Off steam averaging boiler control
  • Up to six (6) remote hard-wired sensors for indoor averaging.
  • Outdoor override sensor shuts down the boiler during warm weather
  • Day/Night/Midday schedule allows up to three (3) different setpoints at different periods of the day.
  • Drop Warmest / Coldest  removes warmest or coldest sensor to stabilize the average temperature
  • Cold Weather Boost detects weather changes and automatically adjusts the setpoint, in response to sudden drop/rise in outside temperature
  • Data logging for boiler runtimes and selected sensor temperature provides data monitoring, which is useful during troubleshooting.
  • RD1606M model – This is the 2-stage model of the RD1606. It can control up to two (2) stages, or a Lo/Hi setup. It includes vacuum pump control for 2-pipe systems.

1612RF/M Wireless Steam Boiler Control

  • Includes all the features of the RD1606  (except for the Drop Warmest/Coldest feature and number of sensors)
  • Up to twelve (12) remote wireless sensors for indoor averaging; the first three (3) sensor inputs allowing for either a hard-wired or wireless sensor
  • Signal strength monitoring  is included for each wireless sensor 
  • 7-year estimated battery life for the wireless sensors
  • High-powered repeaters can be integrated for commercial high-rise buildings. A survey module is recommended to optimize sensor and repeater locations.
  • Heat cycle protection detects a weak sensor signal that may momentarily drop in and out of the Active Average Temperature Range. 
  • 1612RFM model – This is the 2-stage model of the 1612RF. It can control up to two (2) stages, or a Lo/Hi setup. It includes vacuum pump control for 2-pipe systems.

  • 1,2,3,4 Stage configurations depending on the model
  • Night Setback lowers the water setpoint based on outside temperature to maximize fuel savings
  • Morning Boost allows for heat recovery before the start of the Day schedule
  • Room Temperature Monitoring (optional) allows up to 3 room sensors to be used to check indoor temperatures.
  • Auto Boiler Rotation changes lead/lag boiler sequence to prevent boiler wear-and-tear
  • Adjustable Minimum Water Temperature Limit for non-condensing boilers.
  • RD1632 model for a maximum of 2 stages.
  • RD1634 model for a maximum of 4 stages.
