(230V ~);• the control of the maximun delivery temperaturecontrol of the supply to singlecircuits is made by ìfixed pointî mixingsystems (for example Giacomini productR557).The basic function the PM100P control unitfor radiant panel installations is :1.the automatic turning of (or the starting)of the circulation pump according to thecondition of the electrical actuators (R478 or R473 230V~) which are connectedto it;2.safety thermostat with immersionprobe.Moreover the PM100P control unit forradiant panel installations ensures a rapidconnection to the actuators and to thethermostats, without using auxiliary devicessuch as distribution cabinets and/orinterface relay.Function• Supply 230V ~±10%• Possibility to manage independentlyup to 8 ìfreeî contacts from ambientthermostats• Possibility to drive up to 16 electricalactuators R478 (N.O.) or R473 (N.C.)at 230V ~ (8 zones) max 2 for eachcouple of outlet binding-screys.• Visualization of the control state ofthe actuators, by means of LED indicators• Delay in starting the circulator(- 4 minutes) at the opening of one ofthe hydraulic circuits, after the conditionof complete closing.• Connection for the chrono for activationof the circulator and the electricalactuators, with timer• Integrated line fuse: 6,3A delayed• Line switch with luminous indicator• Dimensions in accordance with DIN43880 Standard .• Suitable for installation on DIN EN50022 bar.• Input from thermostats : contactswithout voltage (min.1A @ 230V ~)• Chrono function input : contactwithout voltage (max. 8A @ 230V ~)• Output for circulator : contactwithout voltage (10A res.5A ind.) @230V ~)• Additional controlled output : contactwithout voltage (10A res. 5A ind). @230V ~• Connection binding-screws : screwterminal for wires of 1.5 mm 2• Protections : IP20• Ambient working conditions : 0˜50∞C;10˜90% R.HU. without condensate• Ambient storage conditions : -20˜70∞C; 10˜90% R.HU. withoutcondensateFeaturesProduct in compliance with the European directives 73/23/CEE (low voltage directive)and 93/68/CEE (electromagnetic compatibility directive)

The circulator will defuse itselfautomatically when the last actuatorcloses consequently, when the firstactuator opens, the circulator will beactivated but only after a delay of about4 minutes. In this way the actuator openscompletely and it avoids the circulatorworking on circuits, which are hydraulicallyclosed.The PM100P control unit for radiantpanel installations is designed for usewith the electrical actuators such asR478 (N.O.) by means of the W1 jumper(see fig.1)If you use it with electrical actuatorsmodel R473 (N.C.) you will need to movethe jumper W1 to the right as representedin fig. 2.Each operation that requires the openingof the PM100P shall be effectedwith interrupted supply.Operationfig. 1fig. 2The PM100P has 2 binding-screws (4-5)for an eventual connection to the chronodevice (free contact).This contact, when it is open, disablesall functions of the PM100P. As a consequence,all supplies to the circulatorand to the actuators are interrupted. Ifthe chrono is not used, it is necessary toconnect elctrically the binding-screws.Two screws (7-8) are dedicated to acontrolled line: the 230 V ~ supply willbe present on it only when the chronocontact is closed (or there is the bridgebetween 4 and 5).In addition to the lighting indicators,which indicate the actual condition ofthe connected electrical actuators (8LEDS numbered from 1 to 8, which lightup when the electrical actuators arein open position), the PM100P has a aìgreenî LED (underlined by the symbol ),which shows when the chrono contactis closed.

The intervention threshold is setas default on the value of 50∞C, but theuser can modify by adjusting the potentiometer,as reported on fig.3a-3b.Each operation that requires the openingof the PM100P shall be effectedwith interrupted supply.Safetythermostat55°C55°C40°C80°C 40°C80°Cfig. 3afig. 3bWhen the PM100P, receives from the deliverytemperature sensor a temperaturesignal higher than the set point value, thealarm spy-hole of the delivery temperaturelights up. If the delivery temperaturedoes not fall within the set point limit of4 minutes, then the control unit intervenesand it disables the circulator. Thisaspect is fundamental in order to avoidcontinuous intervention by the safetythermostat, because of delivery temperaturepeaks caused by the interventionslowness of the mixing gears.Overalldimensions4829864660GIACOKLIMA15658fig. 4
