1. Main features
The EKRTWA is a state of the art programmable electronic
thermostat, which regulates your Daikin system, where comfort,
simplicity and energy saving go hand in hand. It is the wired
room thermostat option kit, mainly used for new installations.
The main features are:
■Room temperature control, based on the measurements of
the internal sensor.
■Cooling and heating mode (with possibility to disable cooling
function if not required).
■Off function (with integrated frost protection).
■Comfort and reduced function modes, using the comfort and
reduced setpoint respectively.
■Holiday function mode.
■Weekly schedule timer with 2 custom (◊1+◊2) and 5
predefined (π1~π5) schedules.
- The predefined schedules use the comfort and reduced
setpoints of the comfort or reduced function mode.
- The custom schedules use independent, programmed
setpoints (up to 12 setpoints per day).
-You can lock the schedule timer which allows a temporary
override with the comfort or reduced setpoint by means of
a single key push.
- It is possible to link a custom schedule to cooling and
heating mode.
- Comfort startup control. The schedule timer will
automatically start up in advance, trying to reach the
programmed setpoint at the programmed time.
■Clock (with day and month).
■Key lock function.
■Automatic daylight saving time change.
■Setpoint limitation. Your installer has the possibility to modify
the lower and upper limit of the setpoints. Refer to “Setting
up codes in the installer menu” (code 6® 12+6® 13) in the
installation manual.
