Page 3: Section 1 - Introduction
SECTION 1 INTRODUCTION The SMT 100 is a multi-functional integrated unit providing complete control for the solar heating system. By using microprocessor technology it ensures that the collected energy from the sun is transferred efficiently and harnessed under optimum conditions, while providing valuable information with clarity and ease of use for the user. -
Page 4: Section 2 - Installation / Application
Do not exceed unit ratings as shown on the ratings label. It is advisable to route mains cables away from low voltage or sensor cables. SMT 100 UNIT NOTE: For viewing comfort, the control box should be positioned at eye level. -

TT, the AUX. relay is energised, and when rises above TT, the AUX. relay is de-energised (see SMT 100 Diagram). Connect the output terminal of the AUX. relay to the auxiliary heater or to a contactor (external relay) if the heater has a greater current rating than 3A. -

TF. To adjust TF, see section 3.3.7. 3.2.4 STORAGE TANK LIMIT TEMPERATURE: The SMT 100 has a useful feature to allow maximum temperature from solar to be limited inside the storage tank (cylinder). The controller can switch off the circulation pump if the stored temperature reaches TS (90°C default). -

3.4.2 MANUAL PUMP OVERRIDE The Pump can be manually switched ON at any time by pressing both the keys together. On release of the keys, the pump will switch to its s previous state. Note that the unit must be in DISPLAY mode for this function to work. -
Page 15: Section 4 - Fault Finding
SECTION 4 - FAULT FINDING Problem: Nothing happens when the unit is powered-up. Cause / Remedy: One of the fuses could be blown - check and replace if necessary (refer to specifications for values). If the fuse blows again, contact the agent where the unit was purchased. Problem: The temperature display is fluctuating. -

Questions and answers
meine smt 100 geht immer aus op kein Strom da ist und geht auch wieder an für ein pat stunden
A possible cause for the Thermomax SMT 100 turning off and then back on after a few hours could be overheating due to stagnation, which may damage the automatic air vent or open the pressure relief valve if they are fitted close to the collector. This could lead to temporary shutdown and restarting of the system. Additionally, issues with power connections, such as loose or overheated connections, could also cause intermittent power loss and system resets.
