If he frequency of he power failure were, in an exreme case, greaer han he defros frequency (e.g. a power failure every 8 hours, agains a defros every 1 hours) he conroller would never perform a defros. In a siuaion of his ype, i is preferable o enable defros on sar-up, above all if he defros is conrolled by emperaure (probe on he evaporaor), herefore avoiding unnecessary defross or a leas reducing he running imes. For sysems wih a large number of unis, if selecing defross a sar-up, afer a power failure, all he unis will sar a defros. This may cause volage overloads. To overcome his, parameer d5 can be used, which adds a delay before he defros; he delay mus obviously mus be differen for each uni. d5 represens he ime ha mus elapse beween he sar-up of he conroller and he sar of he defros on sar-up; dd is used o force he sop of he compressor and of he evaporaor fan afer a defros so as o assis he dripping of he evaporaor same. d8 indicaes he high emperaure alarm signal bypass ime afer he end of a defros or when opening he door, if he digial inpu is conneced o he door swich; d9 overrides he compressor proecion imes c1, c2, c3 a he sar of he defros; d/1 and d/2 are used respecively o display he values read by defros probe 1 and 2; dc is used o change he uni of measure (hours or minues) used o coun he imes for parameers di (defros inerval, hours or minues,), dp1 and dp2 (defros duraion). 6.1 Evaporaor fans The evaporaor fans can be managed according o he emperaure measured by he defros and conrol probes.

The value se for AL (AH) is coninuously compared agains he value measured by he conrol probe. Parameer Ad represens he alarm acivaion delay, in minues; he low emperaure alarm (LO) is acivaed only if he emperaure remains below he value of AL for a ime greaer han Ad. The alarm may relaive or absolue, depending on he value of parameer A1. In he former case (A1=), he value of AL indicaes he deviaion from he se poin and hus he acivaion poin for he low emperaure alarm is: se poin - AL. If he se poin changes, he acivaion poin also changes auomaically. In he laer case (A1=1), he value of AL indicaes he low emperaure alarm hreshold. The low emperaure alarm acive is signalled by he buzzer and LO shown on he display. The same applies o he high emperaure alarm (HI), wih AH insead of AL.

For delayed alarms from digial inpu (A4=2, code da), he conac mus remain open for a ime greaer han A7. In he case of an alarm even, a couner sars and generaes an alarm when reaching he minimum ime A7. If during he coun he value measured reurns wihin he hreshold or he conac closes, he alarm is no signalled and he coun is rese. When a new alarm condiion occurs, he coun sars from again. Parameer A6 has a similar meaning o parameer c4 (duy seing).
