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.
