User manual CIAT MICROCIAT MRS 5-1 B

[. . . ] The parameter P00 permits the configuration of the MRS 5-1B for the following 2 types of units : P00 = 0 : ILZHE P00 = 1 : ILZC reversible, without auxiliary device Important : in this configuration, the installer will add a minimum of 30% glycol in the water circuit (risk of freezing). P00 = 2 : ILZC in heating alone (cooling mode not available in this configuration). presence of an oulet for controlling a boiler (see Chapter 5 regulation). The MRS 5-1 B is equipped with a microprocessor ensuring the following functions : Chilled or hot water temperature control. [. . . ] Level 1 : On MRS5 fault display, flashing red LED and J5-5 fault contact closing. p00=0 : compressor , fan and electrical devices stopped (possibility of authorizing operation of electrical auxiliary devices for 48h , see remote relaunching). P00=1 : fan and compressor stopped P00=2 : fan and compressor stopped, boiler operating if required, as per selected mode (whatever P40) Level 2 : On MRS5 fault display, flashing red LED, and closing of J5. In case of fault, there is a neutral available on the terminal box J5, terminal 5 for recovering the unit fault or non fault information. When the unit is in level 1 fault in heating mode only, it is possible to put back into operation the auxiliary electrical devices for 48 hrs (while waiting for the fault repair) : through the Climbox 2 (P04 = 0) by pressing 10 sec. On the Run / Stop key through the all or nothing entries (P04 = 1) by closing the contact J2 11 12 through the MCAD5 (P04 = 2) by pressing key Reset Level or 0 : Automatic acquittal as soon as fault disappears. Level 1 or 2 : Acquittal as soon as fault dispappears and resetting of the card (reset).

In cooling mode : the fan motor assembly operates in speed variation (the speed is function of the condensing temperature models 15 to 65 or function of the pressure on models 90 and 130). In defrosting mode : the fan motor operates only when the condensing pressure is too high (HPD). Furthermore, in order to avoid the risk of HP peaks when the 4-way valve reverses (for units with R407C) it is possible to activate the fan motor by using parameter P11. This safety device is active in all cases D For the ILZHE with R22 and the ILZC with R22/R407C, the heater is controlled by the MRS5. 1B P00 = 0 and P01 = 0 , P002 : If external air T < 2C and if (water return T < 3C or water outlet T < 3C) , heater is supplied. Heater stops as soon as external air T > 4C or (water return T > 5C and water outlet T > 5C). P00 = 1 : If external air T < 13C and if (water return T < 12C or water outlet T < 12C), then the heater is supplied. The heater stops as soon as the external air T > 11C or (water return T > 10C and water outlet T > 10C). D For the ILZHE with R407C (P00 + 0 and P01 = 1) ; the heaters are not controlled by the card as the outlet controls the bypass valve. Water temperature in the water loop whatever the operating mode (cooling - heating - building frost-free mode and stop). [. . . ] When the outside temperature goes above 12C, the circulating pump stops. However, the circulating pump can stop only 3 min. In case of fault from the outside sensor, the circulating pump automatically runs in continuous. When the circulating pump stops, a 7 days " unblocking " tempo is launched. [. . . ]
