Drain the piping system.2. Choose one of the following mounting positions:Electrical Installation• Ensure that the local regulations for electrical installationsare complied with• The connecting terminals are located under the flexibleplastic cover• Make wiring according to the plant documentation. Ifnot available, use the connection diagrams containedin these Installation Instructions• Observe the permissible cable lengths• Switch on power only when commissioning the controllerSettings213 41 LED for test mode / normal operation2 DIP switch block3 Setting slider for setpoint increase or decrease4 Potentiometer for P-band Y1Operating mode:Where?DIP switch block,switches no. 1 and 2What?1 2Heating with boost (setpoint increase)3334P01Maximum limitationmax. 15°max. 15°3333Z02Minimum limitationHeating with ECO (setpoint decrease)Control mode and integral action time:DIP switch block,switches no. 3 and 43 4300 s (VERY SLOW)180 s (SLOW)The controller may not be mounted upside down and the cable may notenter from the top.The minimum immersion length must be 60 mm.60 s (FAST)120 s (MEDIUM)Siemens Building Technologies / HVAC Products CE1G3334xx 05.06.2002 3/20
