Honeywell Sundial RF2 Pack 1 Y9120H2009

  • Wireless enabled timeswitch (ST9120C)
  • Wireless room thermostat (DT92E)

This pack is ideal for adding a room thermostat to a combi boiler or even setting up an individual heating zone elsewhere in your property.

In a heating system with a combination boiler or added zones, with no room thermostat. The existing wiring can be used to provide Boiler Interlock by fitting Sundial RF2 Pack 1. This has a timer to control heating and a built in wireless transceiver to enable a wireless room thermostat, maintaining the traditional layout of separate time control and room thermostat. It can also be used on new systems. Because the room thermostat and the timer communicate, energy saving and operating benefits are also enabled:

Timeswitch override from the thermostat.

†TPI control: Time Proportional and Integral (TPI) control is a method of calculating the demand from a room thermostat, controlling the boiler so that it fires for shorter periods as the temperature approaches the set point. This can offer savings of up to 10% of energy consumption (in a single cycle steady state test).

*Optimum Start: To save energy, let the controls work out when to come on to suit when you want to be warm. Every day the boiler will start at the latest possible moment depending on the weather.

**Delayed Start: Once you have programmed your earliest start time, the controls will delay the boiler firing time on warmer days, when it is possible to save energy.

***Optimum Stop: Saves energy and money by switching off before the normal programme time whenever possible.
