of the controller to heating or cooling mode in 2-pipe operation depending on the inflow temperature; alternatively, this input can be used as an H / C changeover contact. Sensor rupture and short-circuit Fuse: in case of a sensor rupture or sensor short-circuit, the heating is activated with a power-on time of 30% to prevent cooling or frost damage in the room.

KTRRB-117.169
General features: single-room climate controller; ‘off / manual fan / automatic fan’ switch; ‘ventilator 3-stage 0–10 V’ switch; ‘parametrisation 3-stage fan output’ button; ‘heating, cooling, frost protection, sensor rupture or short circuiting of the external sensor’ display; 3-stage fan output 0–10 V with adjustment to individual fan stages or dynamic 0–10 V to activate EC fans ;
MA601500
226.20 / I
ON / OFF: ventilator operation in neutral zone selectable Max. switching current: heating 5 (1) A, cooling 5 (1) A Switching power: heating 1150 W, cooling 1150 W Output signal: Analogue 0–10 V (5 mA) for activating an rpm-controlled fan Hysteresis: approx. 0.5 K
Accessories: Adaptor plate for mounting on flush-mounted socket JZ-17, terminal strips VOOxx (see page 143), suitable valve actuators ZBOOA-010.1xx (see page 146, page 147, suitable external sensors (‘sensor 2’; see ‘Sensor technology’) You can find other / similar controllers with outputs for heating / cooling in the ‘Heating technology’ section (RTBSB / RTBSU).
*With ECO operation, the neutral zone (2 K) is extended by the ECO zone (+ / – 3 K). ECO operation is a savings mode that should be controlled, for example, via a window contact and / or a timer.
