Proline Edition X heating thermostats
 throughput through the external load as large as possible.
2.2. Xpf Setting:
 when oscillating with short period occur (i.e. 30 s)  Xpf lower, otherwise higher,
 in case of bad thermal coupling and large thermal mass  high (i.e. 2 — 5, or even higher),
 in case of good thermal coupling and small thermal mass  small (i.e. 0.2 — 0.7),
 when rapid temperature response is required simple internal control should be preferred. Otherwise
select very small Xpf (0.05 — 0.1).
3. Setting the master controller (PIDT
 Start with setting Auto and proceed with Manual only when necessary.
3.1. Kpe setting:
 Start with empirical values from table ( 0).
 In case of oscillations (with large period, i.e.10 min)  Kpe higher, otherwise lower.
3.2. – Tne/ Tve/ Tde setting:
 Start with empirical values from table ( 0) and with high numbers (Tne = 70 s — 200 s;
Tve = 50 s — 150 s),
 with lower numbers  faster approach, otherwise slower approach with lower oscillations,
 Tve: to reduce overshot  Tve higher, otherwise lower,
 Tde (damping for Tve): in general approximately 10 % of Tve.
4. Correction limitation ( or outflow temperature limitation) ( 7.13.2) and temperature limits (Til/ Tih)
( 7.8.3)
 make settings in accordance with the boundary conditions. Examples:
Heat transfer liquid
Water
Ethanol
Tools to watch the time behavior:
 Graph mode of the Command remote control,
 LAUDA Wintherm PC-program.
